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.
getMetaData call on the Connection object resulting in exception
