Add a static factory method that can be used to create an array
TypeDescriptor with a specific element type. Allows array types
with generic elements to be constructed.
Issue: SPR-9792
JDK 5 introduced an XML-based properties file syntax. This commit
ensures that when such files are supplied as the underlying resource
for a ResourcePropertySource instance, they are routed appropriately
to Properties#loadFromXML as opposed to Properties#load.

- Polished Javadoc for isAnnotationDeclaredLocally() and
isAnnotationInherited().
- Removed unnecessary call to Arrays.asList() in
isAnnotationDeclaredLocally().
Fix serialization warnings by applying @SuppressWarnings("serial")
when appropriate.
In certain cases and for unknown reasons, a correctly-placed
@SuppressWarnings("serial") annotation will fix the warning at the
javac level (i.e. the Gradle command-line), but will produce an
"unnecessary @SuppressWarnings" warning within Eclipse. In these
cases, a private static final serialVersionUID field has been added
with the default value of 1L.
Previously the algorithm used by GenericConversionService to find
converters incorrectly searched for interfaces working up from the
base class. This caused particular problems with custom List
converters as as the Collection interface would be considered before
the List interface giving CollectionToObjectConverter precedence
over the custom converter.
The updated algorithm restores the class search order to behave in the
same way as Spring 3.1.

In particular, avoiding synchronized Sets and Maps wherever possible (preferring a ConcurrentHashMap even instead of a synchronized Set) and specifying appropriate ConcurrentHashMap initial capacities (even if we end up choosing 16).
- Support external Javadoc links using Gradle's javadoc.options.links
- Fix all other Javadoc warnings, such as typos, references to
non-existent (or no longer existent) types and members, etc,
including changes related to the Quartz 2.0 upgrade (SPR-8275) and
adding the HTTP PATCH method (SPR-7985).
- Suppress all output for project-level `javadoc` tasks in order to
hide false-negative warnings about cross-module @see and @link
references (e.g. spring-core having a @see reference to spring-web).
Use the `--info` (-i) flag to gradle at any time to see project-level
javadoc warnings without running the entire `api` task. e.g.
`gradle :spring-core:javadoc -i`
- Favor root project level `api` task for detection of legitimate
Javadoc warnings. There are now zero Javadoc warnings across the
entirety of spring-framework. Goal: keep it that way.
- Remove all @link and @see references to types and members that exist
only in Servlet <= 2.5 and Hibernate <= 4.0, favoring 3.0+ and 4.0+
respectively. This is necessary because only one version of each of
these dependencies can be present on the global `api` javadoc task's
classpath. To that end, the `api` task classpath has now been
customized to ensure that the Servlet 3 API and Hibernate Core 4 jars
have precedence.
- SPR-8896 replaced our dependency on aspectjrt with a dependency on
aspectjweaver, which is fine from a POM point of view, but causes
a spurious warning to be emitted from the ant iajc task that it
"cannot find aspectjrt on the classpath" - even though aspectjweaver
is perfectly sufficient. In the name of keeping the console quiet, a
new `rt` configuration has been added, and aspectjrt added as a
dependency to it. In turn, configurations.rt.asPath is appended to
the iajc classpath during both compileJava and compileTestJava for
spring-aspects.

Added "clearCache()" method to CachingMetadataReaderFactory, for clearing the metadata cache once not needed anymore - in particular when the MetadataReaderFactory instance is long-lived. Also added "setMetadataReaderFactory" method to ClassPathScanningCandidateComponentProvider, analogous to ConfigurationClassPostProcessor.
Prior to this change, the INSTANCE constant one could refer to on
AnnotationAwareOrderComparator actually referred to the constant
declared in the OrderAwareComparator superclass. Thus
AnnotationAwareOrderComparator#INSTANCE did not actually return an
AnnotationAwareOrderComparator but an OrderAwareComparator instead. This
commit introduces a dedicated constant on AnnotationAwareOrderComparator
to avoid this glitch.
Issue: SPR-10038
Develop a new ConcurrentMap implementation that support both weak and
soft entry references. Intended primarily to be used internally to
support fast concurrent caching.
Issue: SPR-9796
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
Improve the #toString method for AnnotationAttributes to print array
values as a comma-separated list. This change is primarily to provide
better variable inspection when debugging code within an IDE.
Remove canBypassConvert() methods from the ConversionService SPI
interface, restoring it to the previous Spring 3.1 incarnation.
Bypassing conversion is now only supported when using a
GenericConversionService.
Issue: SPR-9566
Bypass ObjectToObject conversion when source and object types are
identical and protect against a null source object.
Prior to this commit the TypeDescriptor was used to determine if
conversion was necessary. This caused issues when comparing a
descriptor with annotations to one without. The updated code
now compares using TypeDescriptor.getType().
The ObjectToObject converter will now no longer attempt to convert
null source objects.
Issue: SPR-9933
TypeDescriptor.valueOf now uses GenericCollectionTypeResolver to resolve
Collection and Map element types whereas previously this information was
simply not supported, i.e. null.
Issue: SPR-9257
Prior to this commit conversion between like types would often result in
a copy of the object. This can be problematic in the case of large byte
arrays and objects that do not have a default constructor.
The ConversionService SPI now includes canBypassConvert methods that can
be used to deduce when conversion is not needed. Several existing
converters have been updated to ensure they only apply when source and
target types differ.
This change introduces new methods to the ConversionService that will
break existing implementations. However, it anticipated that most users
are consuming the ConversionService interface rather then extending it.
Issue: SPR-9566
Introduce new ConditionalConversion interface that can be applied to
Converter, ConverterFactory or GenericConverter interfaces to make
them conditional. Prior to this commit the only
ConditionalGenericConverter could be conditional.
Issue: SPR-9928
