I have an update on this issue, hopefully someone can fill me in. I've been testing Hibernate as the persistence engine in Glassfish and once I switched to Toplink in Glassfish, this issue went away. See this thread: http://forums.java.net/jive/thread.jspa?messageID=132930&#132930 I've been using Hibernate 3.2.0.cr2 (and related annotations, entitymanager libs) but I noticed cr3 is out - does this fix this issue? I use both JBoss and Glassfish and would like to use Hibernate as the persistence engine in any and all cases as I use a lot of Hibernate outside of the container as well - I would like to continue to do so!
