Restore the ability to create a TypeDescriptor for a collection or
map where the generics may be null.

Prior to this commit, @ControllerAdvice annotated beans would
assist all known Controllers, by applying @ExceptionHandler,
@InitBinder, and @ModelAttribute.

This commit updates the @ControllerAdvice annotation,
which accepts now base package names, assignableTypes,
annotations and basePackageClasses.

If attributes are set, only Controllers that match those
selectors will be assisted by the annotated class.
This commit does not change the default behavior when
no value is set, i.e. @ControllerAdvice().

This change adds abstractions for opening and managing TCP connections
primarily for use with the STOMP broker support. As one immediate
benefit the change makes the  StompBrokerRelayMessageHandler more
easy to test.

This change consolidates TCP-related logic in the StompRelaySession. As
a result the sub-class SystemStompRelaySession now contains only logic
intrinsic to the shared system session.

This change upgrades reactor to 1.0 RC1 and also removes the
reactor-based message channel in favor of the one available from
org.projectreactor:reactor-spring.

Refactor TypeDescriptor to use ResolvableType in order to retain full
generic type information, in the process fixing MultiValueMap support
in MapToMapConverter.

Issue: SPR-9499

Fix 'missing serialVersionUID' warnings, support for void.class types
and refine resolve() algorithm to support narrowed types.

Consistent use of tabs and remove trailing whitespace.

Unfortunately, the JCache API changed quite a bit since 0.6. We're building against a snapshot of JCache 0.11 now, tracking its way to final after the Public Review Ballot.

Formerly known as the Grails BeanBuilder, now in Spring proper. Based on https://github.com/spring-projects/spring-framework/pull/355 but heavily refactored and restructured.

Issue: SPR-7123

- Support for serialization
- Allow programmatic creation of an array from a given component type
- Allow programmatic creation with given generics
- Extract generics from Class types using Class.getTypeParameters()
- Move TypeVariableResolver to an inner class (and make method private)
- Refine 'resolve()' algorithm

In order to help developers avoid surprises from unintended use of
"@Bean Lite Mode" when referencing classes via @ContextConfiguration in
the TestContext framework, this commit duplicates the previous
discussion of "annotated classes" from the Javadoc for
@ContextConfiguration as a tip in the "Context configuration with
annotated classes" section of the Testing chapter in the reference
manual.

 - Now avoiding NullPointerExceptions in GenericTypeResolver's
   resolveReturnTypeForGenericMethod() in case the supplied ClassLoader
   is null.
 - AutowireUtils.resolveReturnTypeForFactoryMethod() now properly
   asserts that the supplied ClassLoader is not null.
 - Fixed copy-n-paste errors in Javadoc for
   AutowireUtils.resolveReturnTypeForFactoryMethod().

This change adds an alternative UUID generation strategy to use by
default in MessageHeaders. Instead of using SecureRandom for each
new UUID, SecureRandom is used only for the initial seed to be
provided java.util.Random. Thereafter the same Random instance is
used instead. This provides improved performance while id's are
still random but less securely so.

Before this change, async result handling on controller methods failed
to observe type-level annotations annotations. The issue was never
noticed until we started supporting type-level @ResponseBody and the
@RestController meta annotation.

Issue: SPR-10905

Includes revisions of MethodParameter and DependencyDescriptor (in particular towards a reference to the containing class). Also refines several ResolvableType method signatures.

Issue: SPR-9965

We're consistently resolving class names now, and the entire algorithm moved from GenericTypeResolver to the internal AutowireUtils helper in the bean factory package.

Prior to this commit, the template method createDataBinderFactory
would only allow ServletRequestDataBinderFactory as a return type.

This commit updates the method signature and allows
InitBinderDataBinderFactory, a superclass of the previous one.
Then other implementations can override this method and return
other InitBinderDataBinderFactory types.

Issue: SPR-10920

This change adds support for @Header and @Headers annotated method
arguments to spring-messaging. Also supported are arguments of type
MessageHeaders, and MessageHeaderAccessor (including sub-types of
MessageHeaderAccessort as long as they provide a wrap(Message<?>)
static factory method).

This change also renames @MessageBody to @Payload.

Issue: SPR-10985

Fix HttpInvokerClientInterceptor.convertHttpInvokerAccessException to
return the translated exception rather than throwing it. This brings
the method implementation in line with the Java Doc and the obvious
original intent.
