Subject [jira] Assigned: (DERBY-1114) derbynet/testSecMec.java fails intermittently and test exits mysteriously when server is shutdown as part of the testrun.

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.

> 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.
