Myrna van Lunteren commented on DERBY-5617:
-------------------------------------------
I think perhaps there might have been some fall out of this check-in on Feb 16,
with ibm 1.5.
See:
http://people.apache.org/~myrnavl/derby_test_results/main/linux/testSummary-1245297.html
http://people.apache.org/~myrnavl/derby_test_results/main/linux/testlog/ibm15/1245297-suites.All_diff.txt
There are 3 failures (the fourth is DERBY-5377) that look related and there are
some additional similar failures...

-----------------------
> Improve process handling in SpawnedProcess
> ------------------------------------------
>
> Key: DERBY-5617
> URL: https://issues.apache.org/jira/browse/DERBY-5617
> Project: Derby
> Issue Type: Improvement
> Components: Test
> Affects Versions: 10.9.0.0
> Reporter: Kristian Waagan
> Assignee: Kristian Waagan
> Fix For: 10.9.0.0
>
> Attachments: derby-5617-1a-spawnedprocess_improvements.diff
>
>
> SpawnedProcess wraps a java.lang.Process and performs various tasks related
> to process handling. Using external processes from Java is somewhat tricky,
> in part because of sub-optimal behavior in the methods provided by Process.
> I plan to implement the following improvements:
> a) Kill the process after a timeout (the clock starts ticking when you
> create the SpawnedProcess instance).
> b) Don't let interrupts stop SpawnedProcess from waiting for / terminating
> the process.
> c) Clean up the Process properly.
