[jbosscache-issues] [JBoss JIRA] Commented: (JBCACHE-1517) Possibility of upgrading to JGroups 2.8 ?

[Bela Ban (JIRA)]

    [ https://jira.jboss.org/jira/browse/JBCACHE-1517?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12474251#action_12474251 ] 

Bela Ban commented on JBCACHE-1517:
-----------------------------------

The way to get the physical address in JGroups 2.8 is to send a GET_PHYSICAL_ADDRESS event down:

Address logical_addr; // logical address
PhysicalAddress physical_addr; // physical address (interface)

physical_addr=(PhysicalAddress)channel.downcall(Event.GET_PHYSICAL_ADDRESS, logical_addr);

if (physical_addr instanceof IpAddress) {
   IpAddress addr=(IpAddress)physical_addr;
   // use addr (getInetAddress(), getPort())
}
else
  // error

> Can we upgrade JBC 3.2 to use JGroups 2.8? Bela said JGroups 2.6 and 2.8 don't have on the wire 
> compatibility, so if JBC 3.2 and JBC 3.1 clusters would not be able to cluster.
> org.jboss.cache.buddyreplication.NextMemberBuddyLocator is using IpAddress to figure out if candidate 
> and data owner are in the same machine:
>       // assume they're both IpAddresses??
>       InetAddress inetC = ((IpAddress) candidate).getIpAddress();
>       InetAddress inetD = ((IpAddress) dataOwner).getIpAddress();
> There's also some test classes making use of IpAddress, i.e. CacheJmxWrapperTest and GlobalTransactionTest
