Javassist failure in hibernate: invalid constant type: 60
- by Kaleb Pederson
I'm creating a cli tool to manage an existing application. Both the application and the tests build fine and run fine but despite that I receive a javassist failure when running my cli tool that exists within the jar:
INFO: Bytecode provider name : javassist

Since I know the jar is fine as the unit and integration tests run against it, I thought it might be a problem with javassist, so I tried cglib. The bytecode provider then shows as cglib but I still get the exact same stack trace with javassist present in it.
cglib is definitely in the classpath:
$ unzip -l flexipol-jar-with-dependencies.jar | grep cglib | wc -l
383
I've tried with both hibernate 3.4 and 3.5 and get the exact same error. Is this a problem with javassist?
