This is caused by commit https://github.com/jboss-javassist/javassist/commit/dfd0733e1f73853453ff76086481ebec2e88a624

we are trying to remove final modifier from inner class, javassist tries to modify the frozen outher class.

I think the bug is in javassist library, I just put the ticket here to document the defect.
