ASF subversion and git services commented on DERBY-6337:
--------------------------------------------------------

Commit 1594435 from [~mamtas] in branch 'code/trunk'
[ https://svn.apache.org/r1594435 ]

DERBY-6337(derbynet.ServerPropertiesTest.ttestSetPortPriority prints exception java.lang.Exception:
DRDA_InvalidReplyTooShort.S:Invalid reply f rom network server: Insufficient data. but test
passes)

Basically the issue is that sometimes when server is shutting down and a ping is sent to it
around the same time, ping might be able to connect to server but before the ping hand shake
can complete, the server might shutdown thus resulting in the ping client receiving a DRDA_InvalidReplyTooShort.
This is probably why the test in this issue fails intermittently. To fix the issue, if ping
does run into DRDA_InvalidReplyTooShort.S:Invalidreply, we will send another ping after waiting
for a little time, and this time around we should get expected can't connect to server exception
because server is down by now.
