Designed to allow persistence exception translation of
HibernateException types without being forced to use
LocalSessionFactoryBean types.
Committed now in support of the forthcoming introduction of
*SessionFactoryBuilder types.

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.
Issue: SPR-8079
Previously errors were being raised when trying to inject @Value
annotated paramaters such as:
@Feature
public FeatureSpec feature(@Value("#{environment['foo']}") String foo) {
return new FeatureSpec(foo);
}
This is not so much because dependency resolution of @Value-annotated
types was failing, but rather because the 'early bean reference'
proxying mechanism was throwing an exception if any final type was
detected as a parameter. This is of course because final types are
non-subclassable by CGLIB. On review, however, it's obvious that
certain final types must be allowed for injection. @Value injection
is an obvious one, but the rarer case of a Spring bean of type String
or int is another.
The explicit guard against final types as parameters to @Feature methods
has been removed. Final types are still checked for, however, and if
found, no proxing is attempted. The dependency is immediately resolved
against the current BeanFactory and injected into the @Feature method.
This means that @Value injection, @Qualifier injection, etc all work
as expected, but does mean that premature bean instantiation may occur
if a user unwittingly injects non-String, non-primitive final bean types
as @Feature method parameters.
Issue: SPR-7974
CGLIB-enhanced @Configuration subclasses now implement DisposableBean
such that Enhancer.registerStaticCallbacks(subclass, null) is invoked
on container shutdown. This ensures that garbage collection can work
properly and avoids memory consumption issues for applications that
create and destroy many application contexts within the same JVM.
Issue: SPR-7901
context:property-placeholder extends 'propertyPlaceholder' type
defintion once again. This relationship was inadvertently removed in
3.1 M1, and the effect was that XML tooling would raise errors on
use of attributes like 'location'.
The updated schema has also been published to
http://www.springframework.org/schema/context/spring-context-3.1.xsd
Issue: SPR-8037
Prove that injection of special container types such as ResourceLoader,
BeanFactory, etc already works with the current implementation of
@Feature methods.
Issue: SPR-7975
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).
