Out of Memory resulting in heapdump and javacore in test derbynetclientmats (and derbynetmats)
stress.multi with 10.1 with IBM 1.5 JVM after upgrade to SR11 FP1 (from SR10)
----------------------------------------------------------------------------------------------------------------------------------------------------------------------------

                 Key: DERBY-4744
                 URL: https://issues.apache.org/jira/browse/DERBY-4744
             Project: Derby
          Issue Type: Bug
          Components: Test
    Affects Versions: 10.1.3.3
         Environment: windows xp, IBM 1.5 SR11 FP1
            Reporter: Myrna van Lunteren
            Priority: Minor


After upgrade of the IBM 1.5 jvm from SR10 to SR11 FP1, the 10.1 stress.multi test is failing
(out of 6 runs over the last 4 weeks, it failed 5 times) .

This is from the .diff file; there are 8 different heapdumps, this is the first (path has
been simplified):

I'll add a set of dump files.

Logging here for reference, could still be a so-far hidden derby problem or test problem,
although I suspect the jvm.
