> Issue Type: Bug
> Affects Versions: 3.14.0.GA
> Environment: eclipse, powermock 1.4.8, easymock 3, junit 4.8, javassist 3.14.0.GA

> Hi,
> i get this error while using the @PrepareForTest() annotation from the powermock framework.
> This framework uses javassist for bytecode manipulation and i think it's more a javassist bug then a powermock bug.
> the code i try to parse is 2500 lines long (i know bad bad bad code but it's not mine, i only need to test it). i do not want to post all. If you could help me to debug the hole file with javassist to find the methodes or statments that produces this error, i am happy to do so. Is there some debuging level or something to check where javassist crashes?
> Thankyou for now :D
