DefaultHandlerExceptionResolver and ResponseEntityExceptionHandler now
both set the "javax.servlet.error.exception" request attribute to the
raised exception, allowing custom error pages configured via web.xml.
Issue: SPR-9653
While HandlerMethod instances are cached for lookup purposes, a new
ServletInvocableHandlerMethod instance has to be created prior to each
invocation since handlers may have non-singleton scope semantics.
This change reduces the overhead of creating per request instances
by using a logger with a fixed name rather than relying on getClass()
and also by copying introspected method parameters from the cached
HandlerMethod instance.

This commit refactors the BeanInfoFactory so that:
- supports() and getBeanInfo() are folded into one, so that getBeanInfo()
returns null if a given class is not supported.
- CachedIntrospectionResults now uses SpringFactoriesLoader
Prior to this change, CachedIntrospectionResults delegated to
ExtendedBeanInfo by default in order to inspect JavaBean
PropertyDescriptor information for bean classes.
Originally introduced with SPR-8079, ExtendedBeanInfo was designed to
go beyond the capabilities of the default JavaBeans Introspector in
order to support non-void returning setter methods, principally to
support use of builder-style APIs within Spring XML. This is a complex
affair, and the non-trivial logic in ExtendedBeanInfo has led to various
bugs including regressions for bean classes that do not declare
non-void returning setters.
This commit takes advantage of the new BeanInfoFactory mechanism
introduced in SPR-9677 to take ExtendedBeanInfo out of the default code
path for CachedIntrospectionResults. Now, the new
ExtendedBeanInfoFactory class will be detected and instantiated (per its
entry in the META-INF/spring.beanInfoFactories properties file shipped
with the spring-beans jar). ExtendedBeanInfoFactory#supports is invoked
for all bean classes in order to determine whether they are candidates
for ExtendedBeanInfo introspection, i.e. whether they declare non-void
returning setter methods.
If a class does not declare any such non-standard setter methods (the
99% case), then CachedIntrospectionResults will fall back to the
default JavaBeans Introspector. While efforts have been made to fix any
bugs with ExtendedBeanInfo, this change means that EBI will not pose
any future risk for bean classes that do not declare non-standard
setter methods, and also means greater efficiency in general.

- Ensure that ExtendedBeanInfoTests succeeds when building under JDK 7
- Improve handling of read and write method registration where
generic interfaces are involved, per SPR-9453
- Add repro test for SPR-9702, in which EBI fails to register
an indexed read method under certain circumstances

This change fixes a cyclical package dependency.
The change also improves the implementation of
WebAsyncManager.hasConcurrentResult() following the resolution of
Apache issue id=53632 and the release of Apache Tomcat 7.0.30 that
contains the fix.
Update the ReflectiveAspectJAdvisorFactory class to sort candidate
AOP methods based on their annotation first and method name second.
Prior to this the order of aspects created from annotated methods
could differ depending on the underling JVM, as first noticed under
JDK7 in SPR-9729.
- ConvertingComparator and InstanceComparator have been introduced in
support of this change, per SPR-9730.
- A shared static INSTANCE field has been added to ComparableComparator
to avoid unnecessary instantiation costs within ConvertingComparator
as well as to prevent generics warnings during certain caller
scenarios.

Before this commit, the Jaxb2Marshaller required all supported classes
to be annotated with @XmlRootElement. This commit adds a property
'checkForXmlRootElement' (default is true) which allows for un-annotated
classes.
This is especially useful for JAXB2 implementations that can use
external binding files, such as EclipseLink MOXy.
Issue: SPR-9757
This commit avoids eager creation of Environment instances, favoring
delegation of already existing Environment objects where possible. For
example, FrameworkServlet creates an ApplicationContext; both require
a StandardServletEnvironment instance, and prior to this change, two
instances were created where one would suffice - indeed these two
instances may reasonably be expected to be the same. Now, the
FrameworkServlet defers creation of its Environment, allowing users to
supply a custom instance via its #setEnvironment method (e.g. within a
WebApplicationInitializer); the FrameworkServlet then takes care to
delegate that instance to the ApplicationContext created
in #createWebApplicationContext.
This behavior produces more consistent behavior with regard to
delegation of the environment, saves unnecessary cycles by avoiding
needless instantiation and calls to methods like
StandardServletEnvironment#initPropertySources and leads to better
logging output, as the user sees only one Environment created and
initialized when working with the FrameworkServlet/DispatcherServlet.
This commit also mirrors these changes across the corresponding
Portlet* classes.
Issue: SPR-9763
This change fixes a minor bug with the implementation of
ConfigurableEnvironment#merge, introduced in SPR-9444. During a merge
of two environments A and B, where A has default profiles [prod] and B
has default profiles [default] (the so-called 'reserved default
profile'), B would complete the merge process having a collection of
profiles reading [default, prod], which is incorrect.
This commit explicitly ensure's that B's reserved default profile is
removed if A has a set of default profiles greater than zero. If A
consists only of [default], B will inherit it during the merge
correctly; if A consists of [p1, p2], B will result in [p1, p2] as
well; if B consists of [p1] and A of [p2, p3], B will result in
[p1, p2, p3] post-merge.
Issue: SPR-9761, SPR-9444
Prior to this change, AbstractApplicationContext#prepareBeanFactory
registered a bean named 'environment' once and only once within a given
ApplicationContext hierarchy. This worked fine with the expectation
that the Environment object is always delegated downward to children of
that hierarchy. However, with SPR-9444 and the introduction of
ConfigurableEnvironment#merge, this expectation was violated; each
member of an application context hierarchy now maintains its own
distinct Environment instance, which means that by extension that each
application context's underlying BeanFactory should have its own
'environment' bean pointing to that context's environment instance.
This problem could manifest in getting the wrong environment instance
when calling #getBean(Environment) or when @Autowiring an Environment
instance, for example into a @Configuration class. As reported in
SPR-9756, this could result in false negative property lookups or
incorrect results when checking whether a profile is active.
This commit ensures that every bean factory in an application
hierarchy has an 'environment' bean referring to the object returned
from the enclosing ApplicationContext#getEnvironment method.
