Ramesh Reddy resolved TEIID-564.
--------------------------------

    Resolution: Done


This issue is happening because, the abstract class and concrete class were in different class loaders, at that time working package private systematics do not seem work correctly. For correcting this making all abstract methods as "public" visibility.

One another thing noticed is in JBoss AS deploying the fix as the "patch" jar file did not work. It only worked once the patch is combined with original client jar into single jar file.
