I've undeploy war on glasfish and delete generated folder of glassfish, and also occurs.
Glassfish comes with javassist 3.14 version. What version of javassist was in hibernate 4.2.7 that works and now with 4.2.8 not?
I can't use hibernate 4.3 because jpa2.1 is not compatible with jpa2.0 in glassfish 3.1.2.2 (i don't know in other servers)
I can't upgrade hibernate 4.2.7 to 4.2.8 because of javassist dependency.

What can I do?
