Knut Anders Hatlen updated DERBY-5598:
--------------------------------------
Attachment: d5598.diff
This problem looks similar to DERBY-4201, and it reproduces consistently in my
environment with the repro.diff patch attached to that issue.
The problem is that NetworkServerControl.shutdown() returns once the server
socket stops responding, whereas NetworkServerControlImpl.blockingStart()
doesn't print the message about successful shutdown until after the server
socket has been closed. So it is possible that the test checks the contents of
the log after the server socket has been closed, but before the message has
actually been written to the log.
The attached patch attempts to solve this race condition by making the test
wait and re-read the log if the message doesn't show up immediately. This makes
the test pass in my environment, also in combination with the repro patch from
DERBY-4201.
