Description

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.
