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.

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
Refactor internal workings of GenericConversionService in order to
better support future enhancements. This commit should not affect
existing behavior.
Issue: SPR-9927
Prior to this commit, the PropertyResolver API (and therefore the
Environment API) allowed callers a choice between
#resolvePlaceholders and #resolveRequiredPlaceholders for low-level
${placeholder} resolution. However, when calling the higher level
#getProperty variants, users had no control over whether property
values returned with unresolvable ${placeholders} would result in an
exception or simply be passed through.
This commit introduces a #setIgnoreUnresolvableNestedPlaceholders
property via ConfigurablePropertyResolver, defaulting to false, the
value of which is respected by AbstractPropertyResolver#getProperty
method implementations. See the new test in
PropertySourcesPropertyResolverTests for usage examples.
Issue: SPR-9569, SPR-9473
This should be significantly faster than our standard algorithm, for a very common case. Motivated by SPR-9802, even if the fix there uses a different approach, with transaction name determination not calling getMostSpecificMethod at all anymore.
Issue: SPR-9802
Prior to this commit, JibxMarshaller used a SAX ContentHandler to
marshal to StAX XMLEventWriters, which inadvertently resulted in the
deletion of XML comments.
After this commit, JibxMarshaller adapts the XMLEventWriter into an
XMLStreamWriter and comments are preserved.
Issue: SPR-9768
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
Update the ReflectiveAspectJAdvisorFactory class to sort candidate
AOP methods based on their annotation first and method name second.
Prior to this the order of aspects created from annotated methods
could differ depending on the underling JVM, as first noticed under
JDK7 in SPR-9729.
- ConvertingComparator and InstanceComparator have been introduced in
support of this change, per SPR-9730.
- A shared static INSTANCE field has been added to ComparableComparator
to avoid unnecessary instantiation costs within ConvertingComparator
as well as to prevent generics warnings during certain caller
scenarios.
Issue: SPR-9729, SPR-9730
This change fixes a minor bug with the implementation of
ConfigurableEnvironment#merge, introduced in SPR-9444. During a merge
of two environments A and B, where A has default profiles [prod] and B
has default profiles [default] (the so-called 'reserved default
profile'), B would complete the merge process having a collection of
profiles reading [default, prod], which is incorrect.
This commit explicitly ensure's that B's reserved default profile is
removed if A has a set of default profiles greater than zero. If A
consists only of [default], B will inherit it during the merge
correctly; if A consists of [p1, p2], B will result in [p1, p2] as
well; if B consists of [p1] and A of [p2, p3], B will result in
[p1, p2, p3] post-merge.
