----------------------------------------------

             Summary: (7.0.z) IndexOutOfBoundsException when trace logging
                 Key: JGRP-2175
                 URL: https://issues.jboss.org/browse/JGRP-2175
             Project: JGroups
          Issue Type: Bug
    Affects Versions: 3.6.9
            Reporter: Bartosz Spyrko-Śmietanko
            Assignee: Bela Ban
            Priority: Minor
             Fix For: 3.6.11


When running with trace logging, I got couple of these STs:

{code}
Exception in thread "OOB-1,test-NodeE-13479" java.lang.IndexOutOfBoundsException: Index: 4, Size: 2
	at java.util.ArrayList.rangeCheck(ArrayList.java:653)
	at java.util.ArrayList.get(ArrayList.java:429)

	at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617)
	at java.lang.Thread.run(Thread.java:745)
{code}

Seems that part of the list of received messages is removed in handleMessages:864 in

{code}
boolean added=loopback || buf.add(msgs, oob, oob? DUMMY_OOB_MSG : null);
{code}

But the {{size}} is not recomputed afterwards.
