> I think there is a bug in the asm bytecode transformer (considered as "experimental"?).
> The transformer transforms some methods into bytecode which seems to be not valid. The
ASM CheckClassAdapter and the JVM-Verifier fails to check the transformed class with a VerifyError.
> I will provide a TestCase to show this problem.
