I faced heap dump in my project and found jgroups jar is causing issue. (Attached screenshot)
I downloaded Jgroups 2.9 and 3.3 which may have fix for this issue.
But it seems a big task to replace complete jar in my project.
Could you please suggest me, what was the exact solution implemented to fix this memory leakage? So that, I will try to implement same in existing Jgroups.
These are ancient JGroups versions and have not been used in WildFly in at least 4 years.
I would suggest directing your questions to the jgroups mailing list: http://groups.google.com/forum/#!forum/jgroups-dev
