Hi, I tried to start two nodes in colocated topology with JGroups as discovery method (it's defalut for EAP7), but i'm not able to do it. After both nodes are up, this exception starts spamming in logs:

Is there anything wrong with my configs?
I think that problem is in non serializable org.jgroups.JChannel
