Looking at the code which is generating the NPE, it looks like some
persistent entity within your deployment is missing an identifier.
Enable TRACE level logging of org.hibernate package and see which
persistent entity is being processed when this happens. Of course, a
better error message needs to be logged if at all this is a
user/deployment error. So you might want to file a JIRA in Hibernate
project.
