---------------------------------

             Summary: Infinispan 6.0.2 - Upgrading JGROUPS from ver 3.4.1 to ver 3.6.7 or later version
                 Key: ISPN-8821
                 URL: https://issues.jboss.org/browse/ISPN-8821
             Project: Infinispan
          Issue Type: Component Upgrade
         Environment: Oracle Linux - Exalogic/Exadata stack
AS: Weblogic 12.1.3
DB: Oracle 12.1.0.2
JDK: 1.8
            Reporter: Rohit Singh
            Priority: Critical


Ours is a J2EE application (clustered across 4 nodes) internally using Infinispan Cache (Ver 6.0.2) with JGroups (Ver 3.4.1) as transport layer of our cache.

Application had been running perfectly fine, but suddenly on one node, one cache-put got stuck with below stack trace. (Cause being blocked on org.jgroups.protocols.FlowControl$Credit.decrementIfEnoughCredits(FlowControl.java:567)).

Now all further puts are getting stuck - blocked - on the same line on the same node. Other nodes are working fine in this respect.

After discussing with [~belaban], he has suggested to upgrade to a later version of JGROUPS.

*Please suggest on the feasibility of the upgrading JGROUPS.*
