      Hello,

       

      I'm trying to patch a Wildfly 10.0.0.Final with the 10.1.0.Final patch, but I'm running into issues in one of my domain clusters.

       

      I get the following stack trace when the node reboots:

       

      18:16:19,065 WARN  [org.jgroups.protocols.TCP] (TcpServer.Acceptor [7600],null,null) JGRP000006: failed accepting connection from peer: java.lang.NegativeArraySizeException

      I peeked at jgroups' code to try to understand what's going on. It is trying to parse an IP address that's coming from the network, but it's getting a negative byte when it was supposed to receive the size of the IP address. However, this happens shortly after a version compatibility check, so I suppose my usage is a valid one. Also, I have patched successfully other clusters, which puzzles me even more.

       

      Could somebody throw some light on this?

      Thanks in advance
