Dag H. Wanvik commented on DERBY-5223:
--------------------------------------
Thanks for looking at this, Knut. Yes, you are right, I just added it to
resetFromPool as a precaution, I'll add a comment to prevent wrong conclusions
being drawn, though.
Thanks for catching that remaining assert in the thread. Catching and passing
back to the main thread any Throwable (which would include the JUnit exception
from an assert) may be a better approach, though. I'll try that out.

> 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)

> 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.
