But going by what you have mentioned so far, this certainly does not look like a bug in JBoss. anonymous wrote : I dont know if this is related in your issue in http://jira.jboss.com/jira/browse/EJBTHREE-664 The stacktrace looks similar(even though not the same). Are you injecting any resources or is it some simple bean that you are trying? May be the relevant pieces of code might help in identifying the issue.
