I've remove all hibernate*.jar from classpath and add only de hibernate3.jar I've downloaded the source off hibernate-entitymanager to debug from eclipse. I've reached the class that has the error, but I don't know what can I do to resolve it. I'm doing something wrong? I attatch the sources of the classes that takes part on eclipse debug. I don't know how to attach a testcase. The project has more than 200 entities. I've post previously in hibernate forums: https://forum.hibernate.org/viewtopic.php?f=1&t=1002363&p=2424419...
