Description of problem:

Intermittent failure of org.jgroups.tests.UNICAST2_ConnectionTests.testBClosingUnilaterally.
This affects EAP 6.1.0 DR3 and DR4 and was seen before as well. JGroups tags in the last two versions:  JGroups_3_2_6_Final (DR3), JGroups_3_2_7_Final (DR4)

Link to stacktraces - attached as well (EAP 6.1.0 DR4, JGroups_3_2_7_Final):

Comment 1 Richard Janík 2013-03-26 13:46:41 UTC 
Seen in EAP 6.1.0.ER3 as well along with another similar random test fail from UNICAST_ConnectionTests package.

Comment 2 Richard Janík 2013-08-07 13:16:55 UTC 
Seen in EAP 6.1.1.ER4 with JGroups 3.2.7.Final. Bumping to 6.2.0 ?.
Comment 4 Richard Achmatowicz 2014-03-10 14:59:19 UTC 
NOTE: A number of EAP Clustering issues relate to failures in the JGroups testsuite. These failures have been traced to one of several causes which arise when running the JGroups testsuite in the QA lab: 
(i) parallel execution of test cases within the testsuite itself
(ii) parallel execution of testsuites resulting in multicast interference between testsuite executions
(iii) test case timing issues when running on slow machines  

As of EAP 6.3, a modified version of the JGroups testsuite (JGroups version 3.2.13) is being executed sequentially (testsuite parallelism turned off) and with fixes to test case timeouts where applicable. Only the testsuite has been modified/fixed; the product is unchanged. 

EAP 6.3 Clustering issues relating to failures in the JGroups testsuite are being closed if they are no longer appearing as failures in the modified testsuite.
Comment 5 Richard Achmatowicz 2014-03-10 15:00:53 UTC 
This issue no longer appears in JGroups 3.2.13. Closing.
