Bryan Pendleton reassigned DERBY-1114:
--------------------------------------
Assignee: (was: Bryan Pendleton)
I'm not quite sure what's going on with this JIRA issue.
The original problem I was seeing was definitely a JVM bug, which went away when
I upgraded the patch level on my particular JVM.
Others have seen the same symptom, but for them it appears to be a timing issue,
and changing the timing in the test has helped them avoid the problem.
For now, I will unassign myself, as I am not working on the problem and do not
see
it in any of my Derby environments.
> derbynet/testSecMec.java fails intermittently and test exits mysteriously

> The test derbynet/testSecMec.java fails intermittently in a strange way that
> the test actually exits before finishing the full test.
> This issue was noticed by Bryan when he ran derbyall with the derby-1080 fix.
> Some discussion and analysis that has been done is in Derby-1080. Please read
> comments in DERBY-1080. Some main links in
> http://issues.apache.org/jira/browse/DERBY-1080#action_12370260
> http://issues.apache.org/jira/browse/DERBY-1080#action_12370374
> In short: the test does some switching of System.out and System.err streams
> before calling networkserver.shutdown. This code was added to this test as
> part of fix for derby-273. for some reason, the networkserver.shutdown call
> makes the test to exit. One theory is that the network server.shutdown is
> causing the standard out streams to close and thus the test exits.
> -- Need to investigate what is the cause for this intermittent failure and
> how/why networkserver.shutdown is closing the stream or making the test to
> exit prematurely.
