Add BridgeMethodResolver#isJava6VisibilityBridgeMethodPair to
distinguish between (a) bridge methods introduced in Java 6 to
compensate for inheriting public methods from non-public superclasses
and (b) bridge methods that have existed since Java 5 to accommodate
return type covariance and generic parameters.
In the former case, annotations should be looked up from the original
bridged method (SPR-7900). In the latter, the annotation should be
looked up against the bridge method itself (SPR-8660).
As noted in the Javadoc for the new method, see
http://stas-blogspot.blogspot.com/2010/03/java-bridge-methods-explained.html
for a useful description of the various types of bridge methods, as
well as http://bugs.sun.com/view_bug.do?bug_id=6342411, the bug fixed in
Java 6 resulting in the introduction of 'visibility bridge methods'.
Issue: SPR-8660, SPR-7900
Remove all convenience variants of #findAllAnnotationAttributes and
refactor the remaining method to accept a MetadataReaderFactory
instead of creating its own SimpleMetadataReaderFactory internally.
This allows clients to use non-default class loaders as well as
customize the particular MetadataReaderFactory to be used (e.g.
'simple' vs 'caching', etc).
Issue: SPR-8752
Provides a convenient mechanism for activating an additional profile
while preserving those that are already active, as opposed to
calling #setActiveProfiles with the contents of #getActiveProfiles plus
the new profile.
Issue: SPR-8548
isCglibProxy* methods in AopUtils are useful in lower-level modules,
i.e. those that cannot depend on .aop. Therefore copied these methods
to ClassUtils; deprecated the existing ones in AopUtils and now
delegating to the new location; switched all usage of
AopUtils#isCglibProxy* within the framework to use
ClassUtils#isCglibProxy* instead.
For consistency with all other constants representing default
property source names, such as
StandardServletEnvironment#SERVLET_CONTEXT_PROPERTY_SOURCE_NAME and
StandardEnvironment#SYSTEM_ENVIRONMENT_PROPERTY_SOURCE_NAME

Users may now work with command line arguments as a source of
properties for use with the PropertySource and Environment APIs.
An implementation based on the jopt library and a "simple"
implementation requiring no external libraries are are provided
out-of-the box.
See Javadoc for CommandLinePropertySource, JOptCommandLinePropertySource
and SimpleCommandLinePropertySource for details.
Issue: SPR-8482
Prior to this change, the Property class introduced in 3.1 M2 validated
read/write property method pairs based on whether their parameter/return
types were equal to one another. This precluded the valid possibility
of read method that returns a subtype of the write method's parameter
type, and represented a regression against 3.1 M1 and earlier versions.
The implementation now uses isAssignableFrom rather than a straight
equals check against the types.
