Arguments can't fit into locals in class file

Issue

• Our application is failing to run in EAP 6.2.0, there is a very strange 'ClassFormatError' which we do not know what it is and how to handle it.

Caused by: java.lang.ClassFormatError: Arguments can't fit into locals in class file org/example/class_$$_javaassist_0
