Thanks for checking Chris and Lukasz. Since we have not heard back and neither of you can reproduce, this should be closed..

Tested using JDK8 on master, 5.0, and 5.1 and I cannot reproduce the problem.

As part of verifying that this issue affects 5.0, please just set the "Affects version". Leave the "verify-affects-5.0" label and leave the issue in "Awaiting Response" status; these are critical for us to be able to track these verifications and triage them. Thanks.

This bug report does not indicate that the reported issue affects version 5.x. Versions prior to 5.x are no longer maintained. It would be a great help to the Hibernate team and community for someone to verify that the reported issue still affects version 5.x. If so, please add the 5.x version that you verified with to the list of affected-versions and attach the (preferably SSCCE) test case you used to do the verification to the report; from there the issues will be looked at during our triage meetings.

To me it looks like JVM related issue. Attached test case works fine on my machine.
JVM: 1.7.0_25-b17, Java HotSpot(TM) 64-Bit Server VM (build 23.25-b01, mixed mode), vendor: Oracle Corporation
Maven version: 3.1.0
