This reminds me of a test case which sometimes fails for me while running against MySQL and which I did not have time to look at. Maybe this is connected although the test case is single-threaded. The stack trace I am receiving is:

The TestGeneratedValues.java:49 contains:

assertFalse(gv.getUuidstring().equals(gv2.getUuidstring()));

This means UUID generator sometimes generates duplicates.
