Name and version of the database you are using:
DB2 v7 OS 390

The generated SQL (show_sql=true):
None

Debug level Hibernate log excerpt:
None


After walking through Eclipse in debug, I can confirm that the hibernate.cfg.xml file was previously loaded as a resource and in the log excerpt above it was requested again. As it was previously loaded, it was returned from cache, which somehow causes the AnnotationConfiguration to blow up.
