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
Assignee: Shigeru Chiba
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
