Non-deterministic # of results in query

The testJMV4 in MiscTestsJMV is non deterministic : often 11 results, 5 sometimes ;
it gets 5 results (bad) with about 50% probability
if you make a grep for "My" on the test code, you get the expected 11 objects ;
with the notion of cartesian product, one can conceive more results and duplicates
(so the status of tests JMV2* is not clear), but 5 results is clearly an error .
Tests JMV3* succeed.
