If the Hibernate autoconfig is not used to create an EntityManager
then I suppose it's possible that the JpaProperties might be null
when everything else is ready for the event to be published.

There's no test case because I think it's a corner case.

Previously, the versionManagement configuration was resolved as part of
the Boot Gradle plugin being applied. This meant that no dependencies
could be added to it and attempting to do so would result in a failure:
“You can't change a configuration which is not in unresolved state”.
This commit updates ApplyExcludeRules to wrap its processing in a
before resolve action. This defers the resolution of the
versionManagement configuration until one of the project’s other
configurations is being resolved. Fixes #1077

In addition to the above, the transitive exclusions that the Gradle
plugin provides were being lost if custom version management provided
a version for the same dependency. This commit updates
AbstractDependencies to preserve the exclusions from an existing
dependency declaration while using the version from the newer
dependency. This ensures that the exclusions remain while allowing
versions to be overridden. Fixes #1079

Remove superfluous dependencies from spring-boot-starter-tomcat and
spring-boot-starter-jetty which caused gradle based builds to put
too many libraries in `/lib-provided` when building a war.

When there are parent contexts we already had a strategy for registering
the actuator endpoints, but not the regular JMX or Integration MBeans.
This chnage makes the autoconfigs for JMX aware of the parent context.

Also adds a sample with a parent context.
