             Summary: OOBTest method testNonBlockingUnicastOOBMessage  fails to correctly receive all OOB mssages
                 Key: JGRP-1794
                 URL: https://issues.jboss.org/browse/JGRP-1794
             Project: JGroups
          Issue Type: Bug
    Affects Versions: 3.2.13
         Environment: Solaris, RHEL, Windows, HPUX
tcp stack only
            Reporter: Richard Achmatowicz
            Assignee: Bela Ban
             Fix For: 3.2.13


This test fails regularly on multiple platforms. It doesn't fail all the time, but perhaps on 5/10 platform executions.

The test consists of a sender and a receiver. The receiver B will receive OOB messages but blocks on a latch for 25 seconds when it receives a non-OOB message. After 25 seconds, it unblocks and continues receiving

The test does this:
- send 1 regular message from A -> B
- send 9 OOB meesages from A -> B
- wait 20 seconds for messages to arrive
- check that all 9 OOB messages have arrived
- unblock the latch
- check that all 10 message have arrived

The test failures all involve the first 9 OOB messages not arriving completely. For example, sample lists of received messages before the first 20 second interval are:

[3,2,6,8,9,10,4]
[2,3,4,8,9,5]
[2,3,4,8,7,9]
[2,3,5,4,6]

So, it appears that either the messages are slow to arrive or not arriving at all.
