Hi Andreas, thanks for reporting the issue. I have filed a JIRA ticket to track the problem ([1]). Just wondering, is that a constant problem, or did it occur just on those two messages? Another question is, did a reboot of the WildFly server fix the problem? According to the stack, it's some problem related to the transaction execution. Would you be willing to test if the problem occurs on 1.0.3 as well? (see [2]) NOTE: you MUST run the migration tool, before deploying the new WARs ([3]).
