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.
