Error upgrading to latest jgroups in latest JBossCache 1.2.3

[youngm]

When I upgraded to 1.2.3 with the new version jgroups I get periodic exceptions:

11:29:56,205 ERROR [UDP] exception in processing incoming packet
java.lang.NegativeArraySizeException
 at org.jgroups.Message.readFrom(Message.java:634)
 at org.jgroups.protocols.UDP.bufferToMessage(UDP.java:945)
 at org.jgroups.protocols.UDP.handleIncomingUdpPacket(UDP.java:720)
 at org.jgroups.protocols.UDP.run(UDP.java:277)
 at java.lang.Thread.run(Thread.java:595)

Everything appears to work fine I just keep getting that exception.

I have other developers in my LAN working with their own channels if that helps provide any information regarding this problem.

If I revert back to jgroups.jar that came with 1.2.2 everything works fine.

Regards,
Mike

You have other apps running on the same multicast address and port in the same network, change your config and this will go away

Thanks for your help.

Hi all,

I got exactly the same problem but the fact is that this 'other application using same adress/port' is the Group I want to join ... !!
Are all versions of jBossCache / JGroups compatible ?

Thanx a lot.

All members in the same group ned to use the same JGroups/JBossCache versions.

Regarding versions of JGroups that are compatible with specific versions of JBossCache, see http://wiki.jboss.org/wiki/Wiki.jsp?page=JBossCache
