1: What does the NPE cause? Incorrect behavior? This is in the discovery protocol, so I don't think it is a severe error.
2: If you change the JGroups code to print the exception (or set a breakpoint and debug) we'd know what the cause is. 3: Does Infinispan 8.2.2 use JGroups 3.6.8, or did you upgrade JGroups? 4: Is this reproduceable?
