Knut Anders Hatlen updated DERBY-1455:
--------------------------------------
Attachment: derby-1455.diff
derby-1455.stat
Attached a patch which seems to fix the problem. I ran the test 421 times with
the jar files from the 10.2.0.3 snapshot, and it failed 337 times (80% of the
time). With the patch applied, I ran the test 814 times without any failures.
The problem occurs when the test has opened four connections, closes three of
them and runs getRuntimeInfo() on the server. The test expects that there is
one active session on the server, but in some cases, the network server has not
had enough time to clean up after the closed connections, and more sessions are
listed as active.
The patch solves this timing issue by invoking Thread.sleep(1000) before
calling getRuntimeInfo().
