The protected validation methods are analogous to ModelAttributeMethodProcessor now.

The convertJmsInvokerAccessException() method in
JmsInvokerClientInterceptor now correctly returns the converted
exception instead of throwing it.

JmsInvokerClientInterceptor defines a receiveTimeout field but does not
handle such timeout. This commit adds an additional callback that throws
an RemoteTimeoutException instead.

Sub-classes can override the onReceiveTimeout to throw a different
exception or return a fallback RemoteInvocationResult.

With this commit, WebUtils.isValidOrigin() logs an error message instead
of throwing an IllegalArgumentException when Origin header value is
invalid (for example when it does not contain the scheme).

  Fix copy/paste error in Javadoc

Deprecated CommonsPoolTargetSource (supporting commons pool 1.5+) in
favor of CommonsPool2TargetSource with a similar contract.

Commons Pool 2.x uses object equality while Commons Pool 1.x used
identity equality. This clearly means that Commons Pool 2 behaves
differently if several instances having the same identity according to
their `Object#equals(Object)` method are managed in the same pool. To
provide a smooth upgrade, a backward-compatible pool is created by
default; use `setUseObjectEquality(boolean)` if you need the standard
Commons Pool 2.x behavior.

Previously, the `@order` annotation was managed in an inconsistent way
when placed at the implementation level. For simple beans, it was
discovered properly but wasn't for beans requiring a proxy.

OrderComparator.SourceProvider now explicitly allows to return several
order sources; the default implementation returns not only the factory
method (if  any) but also the target class if it happens to be different
from the class of the bean.

This commit adds support for a same origin check that compares
Origin header to Host header. It also changes the default setting
from all origins allowed to only same origin allowed.

Issues: SPR-12697, SPR-12685

 - Added assertions for pre-conditions on method arguments for all
   public utility methods.

 - Introduced additional tests in TestPropertySourceUtilsTests to verify
   the new pre-conditions.

 - Introduced INLINED_PROPERTIES_PROPERTY_SOURCE_NAME constant for the
   name of the MapPropertySource created from inlined properties; the
   name therefore no longer contains the inlined properties, but the
   original values of the inlined properties can now be logged at debug
   level.

 - Simplified tests in InlinedPropertiesTestPropertySourceTests.

Issue: SPR-12721

Spring Framework 4.1 introduced support for @TestPropertySource;
however, the utilities used to parse inlined properties and add test
property sources to the environment are currently private which
prevents reuse by third-party frameworks like Spring Boot.

This commit addresses this issue by making such utilities public.

 - TestPropertySourceUtils is now a public class.

 - Various utility methods in TestPropertySourceUtils have been made
   public.

 - addResourcePropertySourcesToEnvironment() has been renamed to
   addPropertiesFilesToEnvironment().

 - extractEnvironmentProperties() has been renamed to
   convertInlinedPropertiesToMap().

 - All public methods in TestPropertySourceUtils are now fully
   documented.

Issue: SPR-12721

The initial implementation for adding inlined properties configured via
@TestPropertySource to the context's environment did not preserve the
order in which the properties were physically declared. This makes
@TestPropertySource a poor testing facility for mimicking the
production environment's configuration if the property source mechanism
used in production preserves ordering of property names -- which is the
case for YAML-based property sources used in Spring Boot, Spring Yarn,
etc.

This commit addresses this issue by ensuring that the ordering of
inlined properties declared via @TestPropertySource is preserved.
Specifically, the original functionality has been refactored. extracted
from AbstractContextLoader, and moved to TestPropertySourceUtils where
it may later be made public for general purpose use in other frameworks.

Before this change the WebSocketTransportHandler passed
Collections.emptyMap as attributes to the HandshakeHandler because
it didn't matter what attributes the underlying WebSocketSession has
since it is wrapped by the SockJsSession and that's what exposed for
use everywhere.

This change has the WebSocketTransportHandler passing the attributes
from the SockJsSession instead since it's more accurate for the
underlying WebSocketSession to have access to the same map instance
and it allows the HandshakeHandler to change the attributes even if
it doesn't need to do that today.

Issue: SPR-12716

AnnotationListener implementations can now be ordered either using the
`@order` annotation or by implementing the Ordered interface.

Issue: SPR-12410

This commit introduces further regression tests to ensure proper parsing
of inlined properties configured via @TestPropertySource. Specifically,
these additional tests ensure that we do not introduce a bug like the
one raised in Spring Boot issue #1110 [0].

Previously, the exception-handler attribute was not taken care of when
task:annotation-driven is used in AspectJ mode. This commit provides the
expected behavior.
