Subject [jira] Commented: (AMQ-3077) ArraysIndexOutOfBoundsException : -32768 in "BrokerService[xxx] Task" thread
Date Wed, 15 Dec 2010 13:09:03 GMT

    [ https://issues.apache.org/jira/browse/AMQ-3077?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12971673#action_12971673
] 

Gary Tully commented on AMQ-3077:
---------------------------------

yea, at a minimum there should be duplicate detection, only add one that is not already present.

If this is the root of your problem, it should be easy to create a test case that trys to
serialize X brokerInfos, this should blow the boolean output stream.

Also, I think the propagation of peer broker infos should be configurable, it is used to let
the clients know about the list of alternative brokers, so it should only be gathered if necessary.
https://issues.apache.org/jira/browse/AMQ-2632

We need to get some test cases that can demonstrate this problem and can validate and protect
the changes when it is fixed.

> Today this exception is not written in ActiveMQ logs but on the standard output. 
> It seems that happens when network of brokers connections are stopped, but I'm not sure
at all. (the number of "bridge to ... stopped" seems to be the same as the number of Exceptions
detected)
> So I need to dig into this problem to be more precise.
