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.

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, DirectFieldAccessor would ignore fields shadowed
in subclasses, favoring the last field processed, which happens to be
the most super declaration based on the way ReflectionUtils.doWithFields
works.
Because the locally shadowed field may be of a different type that the
superclass declaration, it is most correct to preserve and work with
the shadowed field.

Attempt to access and modify the system environment works on OS X /
Linux but not under Windows. Does not represent any real failure for
production code - the need to modify the system environment is a
testing concern only, and one we can probably live without, considering
the losing battle necessary to make such a hack cross-platform.

AbstractEnvironment and subclasses now register a reserved default
profile named literally 'default' such that with no action on the part
of the user, beans defined against the 'default' profile will be
registered - if no other profiles are explicitly activated.
For example, given the following three files a.xml, b.xml and c.xml:
a.xml
-----
<beans> <!-- no 'profile' attribute -->
<bean id="a" class="com.acme.A"/>
</beans>
b.xml
-----
<beans profile="default">
<bean id="b" class="com.acme.B"/>
</beans>
c.xml
-----
<beans profile="custom">
<bean id="c" class="com.acme.C"/>
</beans>
bootstrapping all of the files in a Spring ApplicationContext as
follows will result in beans 'a' and 'b', but not 'c' being registered:
ApplicationContext ctx = new GenericXmlApplicationContext();
ctx.load("a.xml");
ctx.load("b.xml");
ctx.load("c.xml");
ctx.refresh();
ctx.containsBean("a"); // true
ctx.containsBean("b"); // true
ctx.containsBean("c"); // false
whereas activating the 'custom' profile will result in beans 'a' and
'c', but not 'b' being registered:
ApplicationContext ctx = new GenericXmlApplicationContext();
ctx.load("a.xml");
ctx.load("b.xml");
ctx.load("c.xml");
ctx.getEnvironment().setActiveProfiles("custom");
ctx.refresh();
ctx.containsBean("a"); // true
ctx.containsBean("b"); // false
ctx.containsBean("c"); // true
that is, once the 'custom' profile is activated, beans defined against
the the reserved default profile are no longer registered. Beans not
defined against any profile ('a') are always registered regardless of
which profiles are active, and of course beans registered
against specific active profiles ('c') are registered.
The reserved default profile is, in practice, just another 'default
profile', as might be added through calling env.setDefaultProfiles() or
via the 'spring.profiles.default' property. The only difference is that
the reserved default is added automatically by AbstractEnvironment
implementations. As such, any call to setDefaultProfiles() or value set
for the 'spring.profiles.default' will override the reserved default
profile. If a user wishes to add their own default profile while
keeping the reserved default profile as well, it will need to be
explicitly redeclared, e.g.:
env.addDefaultProfiles("my-default-profile", "default")
The reserved default profile(s) are determined by the value returned
from AbstractEnvironment#getReservedDefaultProfiles(). This protected
method may be overridden by subclasses in order to customize the
set of reserved default profiles.

A subtle issue existed with the way we relied on isCurrentlyInCreation
to determine whether a @Bean method is being called by the container
or by user code. This worked in most cases, but in the particular
scenario laid out by SPR-8080, this approach was no longer sufficient.
This change introduces a ThreadLocal that contains the factory method
currently being invoked by the container, such that enhanced @Bean
methods can check against it to see if they are being called by the
container or not. If so, that is the cue that the user-defined @Bean
method implementation should be invoked in order to actually create
the bean for the first time. If not, then the cached instance of
the already-created bean should be looked up and returned.
See ConfigurationClassPostConstructAndAutowiringTests for
reproduction cases and more detail.

This change is in support of certain polymorphism cases in
@Configuration class inheritance hierarchies. Consider the following
scenario:
@Configuration
public abstract class AbstractConfig {
public abstract Object bean();
}
@Configuration
public class ConcreteConfig {
@Override
@Bean
public BeanPostProcessor bean() { ... }
}
ConcreteConfig overrides AbstractConfig's #bean() method with a
covariant return type, in this case returning an object of type
BeanPostProcessor. It is critically important that the container
is able to detect the return type of ConcreteConfig#bean() in order
to instantiate the BPP at the right point in the lifecycle.
Prior to this change, the container could not do this.
AbstractAutowireCapableBeanFactory#getTypeForFactoryMethod called
ReflectionUtils#getAllDeclaredMethods, which returned Method objects
for both the Object and BeanPostProcessor signatures of the #bean()
method. This confused the implementation sufficiently as not to
choose a type for the factory method at all. This means that the
BPP never gets detected as a BPP.
The new method being introduced here, #getUniqueDeclaredMethods, takes
covariant return types into account, and filters out duplicates,
favoring the most specific / narrow return type.
Additionally, it filters out any CGLIB 'rewritten' methods, which
is important in the case of @Configuration classes, which are
enhanced by CGLIB. See the implementation for further details.

Previously, ExtendedBeanInfo would attempt to process methods named
exactly 'set'. JavaBeans properties must have at least one character
following the 'set' prefix in order to qualify, and this is now
respected by EBI.

Decorator for instances returned from
Introspector#getBeanInfo(Class<?>) that supports detection and inclusion
of non-void returning setter methods. Fully supports indexed properties
and otherwise faithfully mimics the default
BeanInfo#getPropertyDescriptors() behavior, e.g., PropertyDescriptor
ordering, etc.
This decorator has been integrated with CachedIntrospectionResults
meaning that, in simple terms, the Spring container now supports
injection of setter methods having any return type.

Previously, only commas could delimit <beans profile="p1,p2"/>. Now, as
with <bean alias="..."/>, the profile attribute allows for delimiting
by comma, space and/or semicolon.
BeanDefinitionParserDelegate.MULTI_VALUE_ATTRIBUTE_DELIMITERS has been
added as a constant to reflect the fact this set of delimiters is used
in multiple locations throughout the framework.
BDPD.BEAN_NAME_DELIMITERS now refers to the above and has been has been
preserved but deprecated for backward compat (though use outside the
framework is unlikely).

Revert changes to ParserContext, ReaderContext, and XmlReaderContext
These changes cause cross-version incompatibilities at tooling time
-- for instance, an STS version that ships with Spring 3.0.5
classloads the ParserContext defined in that version, whereas it
classloads NamespaceHandlers and BeanDefinitionParsers (by default)
from the user application classpath, which may be building against
3.1.0. If so, the changes introduced to these types in 3.1.0 are
incompatible with expectations in the 3.0.5 world and cause all
manner of problems. In this case, it was NoSuchMethodError due to
the newly-added XmlReaderContext.getProblemReporter() method; also
IncompatibleClassChangeError due to the introduction of the
ComponentRegistrar interface on ParserContext.
Each of these problems have been mitigated, though the solutions
are not ideal. The method mentioned has been removed, and instead
the problemReporter field is now accessed reflectively.
ParserContext now no longer implements ComponentRegistrar, and
rather a ComponentRegistrarAdapter class has been introduced that
passes method calls through to a ParserContext delegate.
Introduce AbstractSpecificationBeanDefinitionParser
AbstractSpecificationBeanDefinitionParser has been introduced in
order to improve the programming model for BeanDefinitionParsers
that have been refactored to the new FeatureSpecification model.
This new base class and it's template method implementation of
parse/doParse ensure that common concerns like (1) adapting a
ParserContext into a SpecificationContext, (2) setting source and
source name on the specification, and (3) actually executing the
specification are all managed by the base class. The subclass
implementation of doParse need only actually parse XML, populate
and return the FeatureSpecification object. This change removed
the many duplicate 'createSpecificationContext' methods that had
been lingering.
Minor improvement to BeanDefinitionReaderUtils API
Introduced new BeanDefinitionReaderUtils#registerWithGeneratedName
variant that accepts BeanDefinition as opposed to
AbstractBeanDefinition, as BeanDefinition is all that is actually
necessary to satisfy the needs of the method implementation. The
latter variant accepting AbstractBeanDefinition has been deprecated
but remains intact and delegates to the new variant in order to
maintain binary compatibility.
