UIMA-AS javadocs are not formatted correctly

It looks like UIMA-AS javadoc is not formatting client API correctly. Marshall discovered that BaseUIMAAsynchronousEngine_impl,createSharedConnection() returns a an instance of a class (SharedConnection) which is an inner class of BaseUIMAAsynchronousEngineCommon_impl. Javadoc insist of using an inner class name with the full package name prefix which makes the column too wide.
One possible fix would be to move the inner class to its own file.

Defer beyond 2.4.2 release
