Thomas H commented on JASSIST-160:
----------------------------------

I have verified the bugfix to the powermock sample and it works fine. Now the new version could be released and add to the maven repository, so that the powermock project can modify the dependency to this version and release a new version themself. Thanks for the quick bugfix.

> We found at least two different cases where inserting bytecode using javaassist results in a class that cannot be loaded with Java 1.7.
> java.lang.VerifyError: Inconsistent stackmap frames at branch target
> java.lang.VerifyError: Bad return type in method
> The exact same code injection on the exact same classes works fine with Java 1.6.
> We upgraded to the latest version of javaassist - 3.16.1.GA, but it didn't solve the problem.
> I'm attaching to this bug a self contained example where you can see both type of errors. 
> More details in "Steps to Reproduce".
