Answer 1

I have today the same issue. (JavaEE 7 and Glassfish 4.0)

The problem seems that the framework check it as String instead with the Class.

String based check (the hypothesis)

When a Exception is twrown, e.getClass() is compared with as string. So you can't use inheritance.

Note that nested classes must be pointed as '$' instead '.' (same as getClass() method).

Class based check

The framework create an instance of the class, and text refer to it, and the class.isInstance() is used to check.

This will need reflection and policy file could break it.

I hope that this response solves future issues.
