[jboss-jira] [JBoss JIRA] (JGRP-1463) FD_SOCK ArrayIndexOutOfBoundsException

Bela Ban commented on JGRP-1463:
--------------------------------
I'm afraid your code is incorrect; we have to get the next member after us ! E.g. for
{A,B,C,D,E} if local_addr=C, the return value should be D. In your code it would always be
A (except if local_addr=A).

Exception in thread "FD_SOCK pinger,Clumpy Test Cluster,CFS-A-tinkywinky"

Presumably there's insufficient synchronization around pingable_mbrs in FD_SOCK.
Similar to JGRP-1411.
