In some scenarios, the ErrorPageFilter will want to forward the request
to an error page but the response has already been committed. One common
cause of this is when the filter’s running on WAS. WAS calls
flushBuffer() (which commits the response), upon a clean exit from a
servlet’s service method.
Previously, the filter would attempt the forward, even if the response
was committed. This would result in an IllegalStateException and a
possibly incomplete response that may also have an incorrect status
code.
This commit updates the ErrorPageFilter to check to see if the response
has already been committed before it attempts to forward the request to
the error page. If the response has already been committed, the filter
logs an error and allows the container’s normal handling to kick in.
This prevents an IllegalStateException from being thrown.
This commit also updates the response wrapper to keep track of when
sendError has been called. Now, when flushBuffer is called, if
sendError has been called, the wrapper calls sendError on the wrapped
response. This prevents the wrapper from suppressing an error when the
response is committed before the request handling returns to the error
page filter.

@PropertySources *can* and should be added in the slot
after the application.properties (code that is part of the
application should have lower precedence than external
configuration).

They all want to create an MBeanServer and when that happens
user sees no MBeans, or sometimes just one set (Spring Core,
Spring Integration or Spring Boot). To harmonise them we
create a @Bean of type MBeanServer and link to it in the
other autoconfigs

This commit changes the default behavior of the HornetQ auto
configuration. Prior to this commit, an embedded broker was only
started when it was requested explicitly by a configuration option.
This is inconsistent with the ActiveMQ support and boot favors the
easiest route. If the necessary classes are available, HornetQ is
embedded in the application by default.
Fixes gh-1029
This commit clarifies how @IntegrationTest can be used as an
alternative of starting the (web) application prior to running the
tests suite.
Fixes gh-667
A callback is added in autoconfig, so that if users inject the EntityManagerFactoryBuilder
into their app and use it to create multiple EntityManagerFactories, they all get the
same deferred DDL behaviour. The deferred DDL can also be disabled by setting
spring.jpa.hibernate.deferDdl=true.
Fixes gh-894
