Remove the 'final' modifier from SingletonBeanFactoryLocatorTests
to work around the "cannot extend final class" error issued when
running all tests. The error was due to confusion with IDEA between
the two variants of SingletonBeanFactoryLocatorTests across
spring-context and spring-beans.
Rename one of the GroovyMessenger classes to GroovyMessenger2.
Previously there were multiple Groovy classes named
'GroovyMessenger', causing a compilation error in certain IDE
arrangements.

Refactor MBean Server reset code from MBeanServerFactoryBeanTests
and reuse in AdvisedJRubyScriptFactoryTests and
AbstractMBeanServerTests.
Issue: SPR-9288
Prior to this commit the testWithLocateExistingAndExistingServer method
would fail if any preceding test called the ManagementFactory
getPlatformMBeanServer() method. In such situations the platform
server is located instead of the expected freshly created server.
These failures are more likely to happen when compiling with JDK 7
due to the fact that the reflection API no longer returns methods
in a consistent order.
Unfortunately there is no easy way to reset the platform MBean server
so the new code must resort to using reflection to access the private
static ManagementFactory.platformMBeanServer field.
Issue: SPR-9288
In the course of this enhancement, the "cache.ehcache" and "cache.jcache" packages moved from spring-context to the spring-context-support module, expecting further transaction-related functionality. Also aligns with the presence of Spring's Quartz support in the spring-context-support module, since Quartz and EHCache are sort of sister projects at Terracotta now.

Implementations of Spring's ImportBeanDefinitionRegistrar interface may
now implement any of the following *Aware interfaces and have their
respective methods called prior to #registerBeanDefinitions:
- BeanFactoryAware
- BeanClassLoaderAware
- ResourceLoaderAware

Refactor DateTimeFormatterFactory into two distinct classes; a general
purpose factory and a specialized FactoryBean. These changes are
modeled after the existing VelocityEngineFactory and
VelocityEngineFactoryBean classes.
Issue: SPR-9959
The DateTimeFormatterFactory introduced in SPR-7121 supports a timeZone
property; however, this property is currently not properly supported.
This commit addresses this issue by ensuring that the timeZone properly
is honored.
Issue: SPR-9953
Added dateFormatter, timeFormatter and dateTimeFormatter properties
to JodaTimeFormatterRegistrar allowing for custom global formatting.
DateTimeFormatterFactory can be used when configuring with XML.
Issue: SPR-7121
Dependency on Joda Time when using the @DateTimeFormat annotation is
now optional. If Joda Time is not present the JDK SimpleDateFormat
will be used to parse and print date patterns. If Joda time is
present it will always be used in preference to SimpleDateFormat.
Issue: SPR-6508
Prior to this commit, calls to ConfigurableEnvironment#addActiveProfile
would cause any active profile values provided via the
"spring.profiles.active" property to be ignored.
Now these two mechanisms can be used in conjunction and work as
expected.
Issue: SPR-9944
Refactor ConfigurationClassParser to recursively find values from
all @Import annotations, combining them into a single unique set.
This change prevents ImportBeanDefinitionRegistrars from being
invoked twice.
Issue: SPR-9925
In particular, the specified object name may use a placeholder for its domain part now, allowing for several instances of the MBean to be registered against the same MBeanServer from different applications.
Issue: SPR-8244
This commit refactors changes introduced in 21760a8 as follows:
- Introduce top-level MessageCodeFormatter interface and
DefaultMessageCodesResolver#setMessageCodeFormatter property to allow
for user-defined message code formatting strategies
- Rename DefaultMessageCodesResolver.Style enum => DMCR.Format
- Refactor DefaultMessageCodesResolver.Format to implement the new
MessageCodeFormatter interface
The result is that users have convenient access to common formatting
strategies via the Format enum, while retaining the flexibility to
provide their own custom MessageCodeFormatter implementation if desired.
See DefaultMessageCodesResolverTests#shouldSupport*Format tests for
usage examples.
Issue: SPR-9707
Introduce new 'style' property to DefaultMessageCodesResolver allowing
for alternative message styles. Current styles are PREFIX_ERROR_CODE
and POSTFIX_ERROR_CODE. The default style retains existing behavior.
Issue: SPR-9707
Allow the body of 'arg-type' XML elements to be used as an alternative to
'match' attribute when defining a 'replace-method' in XML configuration.
This change has been introduced primarily to support the samples printed
in the Apress 'Pro Spring' book.
Issue: SPR-9812
Prior to this commit, @EnableMBeanExport was declared in the
jmx.export.annotation package. This makes logical sense, but
nevertheless creates a package cycle, because @EnableMBeanExport depends
on MBeanExportConfiguration which in turn depends on context.annotation
types like @Configuration, @Bean, and @Role.
context.annotation.config.MBeanExportBeanDefinitionParser, on the other
hand already has dependencies on types in jmx.support. Together, this
means that a package cycle was introduced.
The solution to this is simple: move @EnableMBeanExport and friends from
jmx.export.annotation => context.annotation. This has been the strategy
for other @Enable annotations and for the same reasons. It also makes a
kind of logical sense: just like you find <context:mbean-export> and
<context:load-time-weaver> under the context: XML namespace, so too do
you find their @Enable* counterparts under the context.annotation
namespace.
Issue: SPR-8943
Add support for @EnableMBeanExport annotation allowing @Configuration
classes to easily export all MBeans and @ManagedResources from the
Spring application context. The annotation is functionally equivalent
to the XML <context:mbean-export/> element.
Issue: SPR-8943
Reverted change for @Bean methods that declare FactoryBean as their return type: The effects of trying to create the FactoryBean to find out about its implementation type are too far-reaching. It's better to recommend declaring a specific return type in the method signature if you want the container to specifically react to your implementation type.
Issue: SPR-9857
Includes a change for factory methods that declare their return type as FactoryBean: When asked for a specific type match (e.g. LoadTimeWeaverAware), we do check early singleton instances as well (reusing the instances that we create for getObjectType checks). This is necessary in order to make @Bean method introspection as capable as XML bean definition introspection, even in case of the @Bean method using a generic FactoryBean declaration for its return type (instead of the FactoryBean impl class).

These features require Java 6 or higher due to their dependency on the ResourceBundle.Control class. To some degree, ResourceBundleMessageSource catches up with ReloadableResourceBundleMessageSource now. However, as noted in the javadoc, there are still severe limitations in the standard ResourceBundle class that justify an ongoing investment in our own ReloadableResourceBundleMessageSource (based on the Spring resource abstraction, with manual parsing of properties files).
Issue: SPR-7392
Prior to this change, @ComponentScan required the declaration of
exactly one of the #value, #basePackage or #basePackageClasses
attributes in order to determine which package(s) to scan.
This commit introduces support for base package inference, relaxing the
above requirement and falling back to scanning the package in which the
@ComponentScan-annotated class is declared.
Issue: SPR-9586
Class#getDeclaredMembers returns arbitrary results under JDK7. This
results in non-deterministic execution of JUnit test methods, often
revealing unintended dependencies between methods that rely on a
specific order to succeed.
JUnit 4.11 contains support for predictable test ordering [1], but at
the time of this commit, JUnit 4.11 has not yet been released.
Therefore we are testing against a snapshot version [2], which has been
uploaded to repo.springsource.org [3] for easy access. Note that this
artifact may be removed when JUnit 4.11 goes GA.
- Care has been taken to ensure that spring-test's compile-time
dependency on JUnit remains at 4.10. This means that the spring-test
pom.xml will continue to have an optional <dependency> on JUnit
4.10, instead of the 4.11 snapshot.
- For reasons not fully understood, the upgrade to the 4.11 snapshot
of junit-dep caused NoSuchMethodErrors around certain Hamcrest
types, particularly CoreMatchers and Matchers. import statements
have been updated accordingly throughout affected test cases.
- Runtime errors also occurred around uses of JUnit @Rule and
ExpectedException. These have been reverted to use simpler
mechanisms like @Test(expected) in the meantime.
- Some test methods with order-based dependencies on one another have
been renamed in order to fall in line with JUnit 4.11's new method
ordering (as opposed to actually fixing the inter-test
dependencies). In other areas, the fix was as simple as adding a
tearDown method and cleaning up state.
- For no apparent reason, the timeout in AspectJAutoProxyCreatorTests'
testAspectsAndAdvisorNotAppliedToPrototypeIsFastEnough method begins
to be exceeded. Prior to this commit the timeout value was 3000 ms;
on the CI server under Linux/JDK6 and JDK7, the test begins taking
anywhere from 3500-5500 ms with this commit. It is presumed that
this is an incidental artifact of the upgrade to JUnit 4.11. In any
case, there are no changes to src/main in this commit, so this
should not actually represent a performance risk for Spring
Framework users. The timeout has been increased to 6000 ms to
accommodate this situation.

- Allow reset of GlobalAdvisorAdapterRegistry
Provide a reset() method allowing the GlobalAdvisorAdapterRegistry
instance to be replaced with a fresh instance. This method has
primarily been added to allow unit tests to leave the registry
in a known state.
- Protect against the fact that calls to configuration class methods
my occur in a random order.
Issue: SPR-9779
Prior to this change, AbstractApplicationContext#prepareBeanFactory
registered a bean named 'environment' once and only once within a given
ApplicationContext hierarchy. This worked fine with the expectation
that the Environment object is always delegated downward to children of
that hierarchy. However, with SPR-9444 and the introduction of
ConfigurableEnvironment#merge, this expectation was violated; each
member of an application context hierarchy now maintains its own
distinct Environment instance, which means that by extension that each
application context's underlying BeanFactory should have its own
'environment' bean pointing to that context's environment instance.
This problem could manifest in getting the wrong environment instance
when calling #getBean(Environment) or when @Autowiring an Environment
instance, for example into a @Configuration class. As reported in
SPR-9756, this could result in false negative property lookups or
incorrect results when checking whether a profile is active.
This commit ensures that every bean factory in an application
hierarchy has an 'environment' bean referring to the object returned
from the enclosing ApplicationContext#getEnvironment method.

CGLIB 3 has been released in order to depend on ASM 4, which Spring now
depends on internally (see previous commit).
This commit eliminates spring-beans' optional dependency on cglib-nodep
v2.2 and instead repackages net.sf.cglib => org.springframework.cglib
much in the same way we have historically done with ASM.
This change is beneficial to users in several ways:
- Eliminates the need to manually add CGLIB to the application
classpath; especially important for the growing number of
@Configuration class users. Java-based configuration functionality,
along with proxy-target-class and method injection features now
work 'out of the box' in Spring 3.2.
- Eliminates the possibility of conflicts with other libraries that
may dependend on differing versions of CGLIB, e.g. Hibernate
3.3.1.ga and its dependency on CGLIB 2.1.3 would easily cause a
conflict if the application were depending on CGLIB 3 for
Spring-related purposes.
- Picks up CGLIB 3's changes to support ASM 4, meaning that CGLIB is
that much less likely to work well in a Java 7 environment due to
ASM 4's support for transforming classes with invokedynamic
bytecode instructions.
On CGLIB and ASM:
CGLIB's own dependency on ASM is also transformed along the way to
depend on Spring's repackaged org.springframework.asm, primarily to
eliminate unnecessary duplication of ASM classfiles in spring-core and
in the process save around 100K in the final spring-core JAR file size.
It is coincidental that spring-core and CGLIB currently depend on the
exact same version of ASM (4.0), but it is also unlikely to change any
time soon. If this change does occur and versions of ASM drift, then
the size optimization mentioned above will have to be abandoned. This
would have no compatibility impact, however, so this is a reasonable
solution now and for the forseeable future.
On a mysterious NoClassDefFoundError:
During the upgrade to CGLIB 3.0, Spring test cases began failing due to
NoClassDefFoundErrors being thrown from CGLIB's DebuggingClassWriter
regarding its use of asm-util's TraceClassVisitor type. previous
versions of cglib-nodep, particularly 2.2, did not cause this behavior,
even though cglib-nodep has never actually repackaged and bundled
asm-util classes. The reason for these NoClassDefFoundErrors occurring
now is still not fully understood, but appears to be due to subtle JVM
bytecode preverification rules. The hypothesis is that due to minor
changes in DebuggingClassWriter such as additional casts, access to
instance variables declared in the superclass, and indeed a change in
the superclass hierarchy, preverification may be kicking in on the
toByteArray method body, at which point the reference to the missing
TraceClassVisitor type is noticed and the NCDFE is thrown. For this
reason, a dummy implementation of TraceClassVisitor has been added to
spring-core in the org.springframework.asm.util package. This class
simply ensures that Spring's own tests never result in the NCDFE
described above, and more importantly that Spring's users never
encounter the same.
Other changes include:
- rename package-private Cglib2AopProxy => CglibAopProxy
- eliminate all 'cglibAvailable' checks, warnings and errors
- eliminate all 'CGLIB2' language in favor of 'CGLIB'
- eliminate all mention in reference and java docs of needing to add
cglib(-nodep) to one's application classpath

For legacy reasons, a MockEnvironment implementation already exists in multiple places within Spring's test suite; however, it is not available to the general public.
This commit promotes MockEnvironment to a first-class citizen in the spring-test module, alongside the existing MockPropertySource.
In addition, the following house cleaning has been performed.
- deleted MockPropertySource from the spring-expression module
- deleted MockEnvironment from the "spring" integration testing module
- updated test copies of MockPropertySource and MockEnvironment
- documented MockEnvironment and MockPropertySource in the testing
chapter of the reference manual

@Async executor qualification has been backported to 3.1.2. This commit
updates all @since tags appropriately, as well as carrying over the
changes backported to the spring-task-3.1 schema.
Issue: SPR-6847, SPR-9443
java.util.concurrent's ScheduledExecutorService and its #schedule*
methods allow for an 'initialDelay' parameter in milliseconds.
Similarly, Spring's TaskExecutor abstraction allows for a concrete
'startTime' expressed as a Date. However, Spring's <task:scheduled> XML
element and @Scheduled annotation have, to date, not allowed for an
initial delay parameter that can be propagated down to the underlying
TaskScheduler/ScheduledExecutorService.
This commit introduces initial-delay and #initialDelay attributes to
task:scheduled and @Scheduled respectively, both indicating the number
of milliseconds to wait before the first invocation of the method in
question. Specifying a delay in this fashion is only valid in
conjunction with fixed-rate and fixed-delay tasks (i.e. not with cron
or trigger tasks).
The principal changes required to support these new attributes lie in
ScheduledTaskRegistrar, which previously supported registration of
tasks in the form of a Runnable and a Long parameter indicating (in the
case of fixed-rate and fixed-delay tasks), the interval with which the
task should be executed. In order to accommodate a third (and optional)
'initialDelay' parameter, the IntervalTask class has been added as a
holder for the Runnable to be executed, the interval in which to run
it, and the optional initial delay. For symmetry, a TriggerTask and
CronTask have also been added, the latter subclassing the former. And a
'Task' class has been added as a common ancestor for all the above.
One oddity of the implementation is in the naming of the new
setters in ScheduledTaskRegistrar. Prior to this commit, the setters
were named #setFixedDelayTasks, #setFixedRateTasks, etc, each accepting
a Map<Runnable, long>. In adding new setters for each task type, each
accepting a List<IntervalTask>, List<CronTask> etc, naturally the
approach would be to use method overloading and to introduce methods
of the same name but with differing parameter types. Unfortunately
however, Spring does not support injection against overloaded methods
(due to fundamental limitations of the underlying JDK Introspector).
This is not a problem when working with the ScheduledTaskRegistrar
directly, e.g. from within a @Configuration class that implements
SchedulingConfigurer, but is a problem from the point of view of the
ScheduledTasksBeanDefinitionParser which parses the <task:scheduled>
element - here the ScheduledTaskRegistrar is treated as a Spring bean
and is thus subject to these limitations. The solution to this problem
was simply to avoid overloading altogether, thus the naming of the new
methods ending in "List", e.g. #setFixedDelayTasksList, etc. These
methods exist primarily for use by the BeanDefinitionParser and are
not really intended for use by application developers. The Javadoc for
each of the new methods makes note of this.
Issue: SPR-7022
In anticipation of substantive changes required to implement "initial
delay" support in the <task:scheduled> element and @Scheduled
annotation, the following updates have been made to the components and
infrastructure supporting scheduled task execution:
- Fix code style violations
- Fix compiler warnings
- Add Javadoc where missing, update to use {@code} tags, etc.
- Organize imports to follow conventions
