Subject [jira] [Issue Comment Edited] (DERBY-5081) Intermittent failure in InterruptResilienceTest: IO thread times out waiting for another thread to recover channel
Date Mon, 09 May 2011 16:51:03 GMT

    [ https://issues.apache.org/jira/browse/DERBY-5081?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13030155#comment-13030155

--------------------------------------------------------------

Also on this platform combo, I sometimes see another error which I suspect is related:

..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)

In this case also, the reason is that a tread's interrupted flag was lost (during re-preparing
a statement). It could be the same underlying error. If, when we get a fix for the JDK 7,
it doesn't remove this symptom, we should file a different issue for it. 

[edit: I filed DERBY-5223 for this - it is a different issue]
