Prior to this change, @Autowired injection against an instance of a
subclass having different visibility than its superclass would fail
if the @Autowired method is declared only in the superclass. This is due
to an apparent change in the rules around bridge method generation
between Java 5 and Java 6, and possibly even varying across compiler
vendors.
Now, BridgeMethodResolver is used consistently when detecting
@Autowired, @Inject and @Resource metadata to bypass these bridge
methods if they exist.

- introduced processContextConfigurationAttributes() method in SmartContextLoader SPI
- refactored AnnotationConfigContextLoader, AbstractContextLoader, AbstractGenericContextLoader, ContextLoaderUtils, and TestContext implementations to take advantage of the SmartContextLoader SPI, MergedContextConfiguration, and ContextConfigurationAttributes
- deleted ResourceTypeAwareContextLoader
- deleted ContextLoaderUtils.LocationsResolver and implementations
- moved context key generation from TestContext to MergedContextConfiguration
Prior to this change, AbstractAutowireCapableBeanFactory did not support
a default ParameterNameDiscoverer. This meant that attempting to use
<constructor-arg name=".."> syntax would fail (with a fairly obscure
exception) as that feature depends on a ParameterNameDiscoverer to
introspect the constructor arguments.
This lack of a default was originally intended to avoid a dependency on
ASM, but now that (a) .asm is a built-in module and (b) .beans has a
non-optional compile-time dependency on .asm, there is no reason not to
provide this default.
The net effect is that in a number of locations throughout the
framework, namely in GenericApplicationContext and
AbstractRefreshableApplicationContext, it is no longer necessary to
explicitly call AACBF#setParameterNameDiscoverer. This also means that
using a naked BeanFactory (likely for testing scenarios) is that much
easier.

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.

As of SPR-8093, jmxremote_optional.jar is present on the build
server in jre/lib/ext, but it is not by default present on local
developer / user machines, meaning that the build ends up broken
by default.
