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
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.

Issue: SPR-9783
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.
