[jboss-jira] [JBoss JIRA] Updated: (JBAS-6307) Cross-cluster cross-talk on JBM-DATA channel

[Brian Stansberry (JIRA)]

     [ https://jira.jboss.org/jira/browse/JBAS-6307?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Brian Stansberry updated JBAS-6307:
-----------------------------------

    Workaround Description: 
Replace the complex syntax like:
mcast_addr="${jboss.messaging.datachanneludpaddress,jboss.partition.udpGroup:228.6.6.6}"
with:
mcast_addr="${jboss.partition.udpGroup:228.6.6.6}"
Prefer keeping the jboss.partition.udpGroup property as that can easily be set from the command line via the -u or --udp startup option.

                Workaround: [Workaround Exists]

>          Issue Type: Bug
>      Security Level: Public(Everyone can see) 
>          Components: Clustering, JMS (JBoss Messaging)
>    Affects Versions: JBossAS-5.0.0.GA
>            Reporter: Brian Stansberry
>            Assignee: Brian Stansberry
>             Fix For: JBossAS-5.0.1.CR1
>
>
> The configuration syntax in the jbm-data protocol stack config's MPING.mcast_addr attribute is not understood by the JGroups parser; it's syntax only supported by the String property replacement code in jboss-common-core.jar.
> <MPING timeout="5000" mcast_addr="${jboss.messaging.datachanneludpaddress,jboss.partition.udpGroup:228.6.6.6}"
> will be evaluated by JGroups as "use value for system property 'jboss.messaging.datachanneludpaddress,jboss.partition.udpGroup', if not found use 228.6.6.6".  Which results in 228.6.6.6.
> Fix is to replace with 
> <MPING timeout="5000" mcast_addr="${jboss.partition.udpGroup:228.6.6.6}"
> in which case setting -u at AS startup will set jboss.partition.udpGroup, which JGroups will find and use.
