Paris Apostolopoulos did you find a solution for running Hibernate 4.2.8+ on WebSphere 8+?
I am experiencing the same problem as described here but with WebSphere 8.0. I guess it has something to do with a javassist jar from the app server being visible to application code that shouldn't. Fortunately it is not so critical for me to update hibernate, but still I have this bad feeling, that this will come back to me
I would be very grateful if you could share any information!
