Description Martin Oberhuber CLA 2011-01-10 10:05:08 EST 
Seen during the N-build on hudson.eclipse.org on 10-Jan-2011:
https://hudson.eclipse.org/hudson/job/cbi-tm-3.2-nightly/188/
The error does not always happen, might be timing dependent.

junit.framework.AssertionFailedError: null
	at org.eclipse.rse.tests.subsystems.files.FileServiceArchiveBaseTest.testOpenFileFromTarArchive(FileServiceArchiveBaseTest.java:925)
	at org.eclipse.rse.tests.core.RSECoreTestCase.runTest(RSECoreTestCase.java:425)
Comment 1 Martin Oberhuber CLA 2011-01-10 11:18:52 EST 
FWIW, this happened during the

   FileServiceTgzArchiveTest.testOpenFileFromTarArchive

test, and it also occurred on the Jan 6 Hudson build (but not on Jan 7).

Xuan can you please look at this as just discussed in the monthly meeting?
Comment 3 Xuan Chen CLA 2011-01-14 11:35:30 EST 
I cannot reproduce it using my development driver.

I will probably add more messages to help narrow down the failure.

Comment 5 Martin Oberhuber CLA 2011-02-07 10:26:45 EST 
As of 3.3M5, Hudson shows an AssertionFailed instead of the NPE:
