NullPointerException on StressMultiTest in language layer with ibm1.5 on Windows machine
----------------------------------------------------------------------------------------

                 Key: DERBY-4721
                 URL: https://issues.apache.org/jira/browse/DERBY-4721
             Project: Derby
          Issue Type: Bug
          Components: Test
            Reporter: Mamta A. Satoor


Saw NPE for testStressMulti on trunk(10.7 revision 956758) on a windows machine with ibm15.
May be related to commit made for DERBY-4279,  since it seems to have caused some other NPEs
in StressMultiTest in the Tinderbox too.

The stack trace looks as follows 
1) testStressMulti(org.apache.derbyTesting.functionTests.tests.multi.StressMultiTest)junit.framework.AssertionFailedError:
