Restore the custom title page of the reference manual in order to
remove the large list of authors on the first page.
Note: This change will require updating to version 0.1.7 of the
docbook-reference-plugin when it is released.

Remove all xsd versions from the reference manual samples in favor of
"versionless" XSDs. For example, spring-beans-3.0.xsd becomes
spring-beans.xsd
Issue: SPR-10010
Prior to this commit many imagedata elements were duplicated in
order to configure PDF sizes. Since HTML generation is configured
to ignore image scaling altogether this was unnecessary duplication.
Issue: SPR-10033
Convert all docbook XML files to well-formed docbook 5 syntax:
- Include xsi:schemaLocation element for tools support
- Convert all id elements to xml:id
- Convert all ulink elements to link
- Simplify <lineannotation> mark-up
- Fix misplaced </section> tags
- Fix <interface> tags to <interfacename>
- Cleanup trailing whitespace and tabs

Since web applications declaring a Servlet 2.3 web.xml become really rare now, we're finally deprecating Spring's own ExpressionEvaluationUtils class. As a consequence, we're also setting "springJspExpressionSupport" to false by default, avoiding the potential double EL evaluation problem on pre-Servlet-3.0 containers.

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.

Previously, CachedIntrospectionResults had three modes of caching, with the intermediate mode relying on WeakReferences in the JDK PropertyDescriptor implementation. Since the JDK is actually using SoftReferences there these days, losing information in case of a GC run with tough memory constraints, we want to allow for hard references in PropertyDescriptor objects and therefore use a full WeakReference for the CachedIntrospectionResults object itself.
Issue: SPR-10028
This change revisits the implementation of ExtendedBeanInfo, simplifying
the overall approach while also ensuring that ExtendedBeanInfo is fully
isolated from the BeanInfo instance it wraps. This includes any existing
PropertyDescriptors in the wrapped BeanInfo - along with being copied
locally into ExtendedBeanInfo, each property descriptor is now also
wrapped with our own new "simple" PropertyDescriptor variants that
bypass the soft/weak reference management that goes on in both
java.beans.PropertyDescriptor and java.beans.IndexedPropertyDescriptor,
maintaining hard references to methods and bean classes instead. This
ensures that changes we make to property descriptors, e.g. adding write
methods, do not cause subtle conflicts during garbage collection (as was
reported and reproduced in SPR-9702).
Eliminating soft/weak reference management means that we must take extra
care to ensure that we do not cause ClassLoader leaks by maintaining
hard references to methods, and therefore transitively to the
ClassLoader in which the bean class was loaded. The forthcoming
SPR-10028 addresses this aspect.
See the updated ExtendedBeanInfo Javadoc for further details.

The new jdiff task generates a report of API differences between the
current version (i.e. the value of `version` in gradle.properties) and
any older version of the framework, as specified by -DOLD_VERSION at
the command line, or defaulting to `previousVersion` in
gradle.properties.
Running the command requires a separate clone directory pinned to the
desired old version, as specified by -DOLD_VERSION_ROOT at the command
line. This creates challenges from a build automation perspective,
largely because Gradle doesn't (yet) have APIs for working with Git.
This task may be further automated and included in nightly CI runs, but
in the meantime, a number of reports back to 3.1.3.RELEASE have been
generated manually and uploaded to [1], where one can now find the
following entries in the directory listing:
- 3.1.3.RELEASE_to_3.2.0.RC1
- 3.2.0.M1_to_3.2.0.M2
- 3.2.0.M2_to_3.2.0.RC1
- 3.2.0.RC1_to_3.2.0.BUILD-SNAPSHOT
Ideally, the final entry there would be kept up-to-date on a daily
basis - again we may revisit doing so in the future. Going forward,
reports will be generated and uploaded manually on an as needed basis
and as part of the release process.
The goal of these reports are as follows:
- to ease the process of ensuring backward compatibility
- to aid in code reviews, particularly when reviewing large pull
requests
- to ease the process of creating migration guides for project
maintainers, i.e. to help us remember what's changed
- to allow ambitious end-users to discover what's been changing at the
API level without without needing to wait for detailed "what's new in
version X" and/or migration guide documentation
See documentation in jdiff.gradle for usage details.
Note that the jdiff-1.1.1 distribution as downloaded from [2] has been
added wholesale to the source tree under gradle/jdiff instead of
uploading JDiff jars to repo.springsource.org as we would normally do.
This is due to some unfortunate limitations in the implementation of the
jdiff ant task that require a phisical JDIFF_HOME directory. Checking in
the jars and various resources represents the simplest and most
pragmatic solution to this problem, though ambitious contributors are
free to do what's necessary to arrive at a more elegant arrangement.

Previously the publish-maven.gradle only supported having a single
artifact be marked as optional or provided. This causes problems now
that we are building modules that support multiple versions of an
artifact. For example, we compile against two versions of Tiles
artifacts with identical names, both of which need to be marked
optional.
This updates publish-maven.gradle to find all the artifacts and mark
them as optional as apposed to the first entry.
The change to support generic @RequestBody arguments introduced in
3.2 M2 also introduced a regression in reading arguments that are
type variables. This change fixes the issue.

Update SpEL boolean operators to always call the ConversionService
for null values. Primarily to allow null values to be treated as
false by overriding GenericConversionService.convertNullSource().

Replace reference to aspectjrt.jar with aspectjweaver.jar since
aspectjrt is a subset of aspectjweaver and the full jar is required
by Spring.
Issue: SPR-8896
Update reference manual with details of Java configuration @Enable*
annotations. Examples of Java style @Configuration is provided
when appropriate alongside existing XML samples.
Several existing @Configuration samples have been changed to placing
the @Enable annotation below the @Configuration annotation.
This has been done to provide consistency with existing Javadoc.

When a controller method declares Callable or DeferredResult as its
return value, and returns null, async processing will not start and
the request will be considered "handled" by the controller method.
Issue: SPR-9951
Tiles 3 has modified packages and classes as well as additional
dependencies, notably "tiles-request-api", which is a request/response
abstraction independent of Servlet and JSP APIs.
In order to have both Tiles 2 and Tiles 3 integrations, the source for
the Tiles 3 integration is in a separate project spring-webmvc-tiles3.
The build process merges the compiled Tiles 3 integration classes into
the spring-webmvc module so in effect it contains both the Tiles 2 and
the Tiles 3 integrations.
This change originated as a pull request at spring-framework-issues:
https://github.com/SpringSource/spring-framework-issues/pull/30

Update Javadoc to indicate that the getAsyncExecutor() method may be
optionally annotated with @Bean and in such circumstance the
executor.initialize() method need not be called.
