> This testcase has been tested with 3.1.3 and 3.2.0-ga.
> 2nd problem:
> There is also another situation in the testcase which I found through serendipity which causes a NPE inside hibernate because I misspelled "r" as "rec".  Check out the commented out section and swap over the createQuery() lines to demonstrate that NPE.
