Description
Seen in our clustering failover tests for remote stateful EJBs - using legacy EJB client 3.x.
Setup: 4 node cluster, one node at the time is shut down gracefully, while 2000 standalone clients keep calling the application.
After perf19 was gracefully shut down (time 2017/11/08 11:34:06:783 EST), 3 clients logged this error message:
2017/11/08 11:34:06:234 EST [ERROR][Runner - 639] HOST perf17.mw.lab.eng.bos.redhat.com:rootProcess:c - Error getting response. <java.lang.ArrayIndexOutOfBoundsException: 5>

This error was seen only in one scenario (eap-7x-failover-legacy-ejb-ejbremote-shutdown-dist-sync) so far and seems to be very rare.
