Build Identifier: Implementation-Version: 2.3.2.v20111125-r10461

Similar to Bug 350516

I have NPE in eclipselink 2.3.2 release, because the parentClass is null.
This is the statement "243:while (! parentClass.isObject()) {"




Workaround is to extend the Base class  explicit from Object, like  
public class Base extends Object {


Please fix like
"243:while (parentClass!=null && !parentClass.isObject()) {"
