> Sometimes we have this this stack trace on the log from SuitesAll:
> .Exception in thread "WorkerThread. Thread#5" junit.framework.AssertionFailedError
>         at junit.framework.Assert.fail(Assert.java:47)
>         at junit.framework.Assert.assertTrue(Assert.java:20)
>         at junit.framework.Assert.assertTrue(Assert.java:27)
>         at org.apache.derbyTesting.functionTests.tests.store.InterruptResilienceTest$WorkerThread.run(InterruptResilienceTest.java:430)

> This happens sometimes when the application thread's interrupt flag is set before we
enter a Derby API call, but the flag is cleared on return contrary to our specified behavior.

> I can reproduce this every 20 runs or so on Linux with JDK7, but it has been seen also
on Windows, so it is not VM specific.
