Failed to transform class with name com.some.class. Reason: null
----------------------------------------------------------------

                 Key: JASSIST-141
                 URL: https://issues.jboss.org/browse/JASSIST-141
             Project: Javassist
          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
            Reporter: Andreas Don'tAskDon'tTell

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

Yours,
Andreas
