What failure are you pursuing?
The following one occurs frequently on Gump/buildbot:
[[[
Testcase: testCometConnectorStop took 4.078 sec
FAILED
Comet END event not received
junit.framework.AssertionFailedError: Comet END event not received
at
org.apache.catalina.comet.TestCometProcessor.testCometConnectorStop(TestCometProcessor.java:293)
]]]
In the main stdout file there occasionally are also a lot of NPE like
