It seems to be linked to the *number* *of* *tests* in
dbaccess/qa/complex/dbaccess/RowSet.java

I never got it when I commented out any one of the "@Test" there. It
seems to happen (sometimes) during/after the
 testConcurrentAccess(m_resultSet);
call, maybe only when one of the threads actually throws an exception
that is ignored, but this seems to be related to the number of tests
run before that.

To ensure that "testConcurrentAccess" fails successfully, revert
d6d19acaca14d5b45ffb0db0028f17567d196c4d
and probably also
e9d055bf67d2ad600d2efa58a4c8b8bbcedf348c

(although Miklos and Linux Gerrit Gerrit_Debug got it that way also
 with d6d19acaca14d5b45ffb0db0028f17567d196c4d applied... Something
 I'll have to debug in some way. I'm trying on another machine now.)
