      See the following stack trace:

      [ERROR] 2016-07-09 14:26:05 [UDP-multicast receiver,shared=jgroups-shared-transport] - JGRP000030: null: failed handling incoming message: java.lang.ArrayIndexOutOfBoundsException: -1
      java.lang.ArrayIndexOutOfBoundsException: -1

      Stepping through the code with the debugger shows that the following line is failing at ClassConfigurator.get() with magic = -1 thus the java.lang.ArrayIndexOutOfBoundsException

      return magic < 1024 ? magicMap[magic] : (Class)magicMapUser.get(Short.valueOf(magic));

      See attached jgroups.xml for configuration. This showed up when upgrading to 3.6.10 from 3.6.8 which worked fine.
