If -b 0.0.0.0 is used, do not pass wildcard addresss through to JGroups
-----------------------------------------------------------------------

                 Key: JBAS-4181
                 URL: http://jira.jboss.com/jira/browse/JBAS-4181
             Project: JBoss Application Server
          Issue Type: Task
      Security Level: Public (Everyone can see)
          Components: Clustering
            Reporter: Brian Stansberry
         Assigned To: Brian Stansberry
             Fix For: JBossAS-5.0.0.Beta2, JBossAS-4.2.0.GA


If JGroups tries to bind to 0.0.0.0 you get nasty effects like:

0.0:2898, my view is [0.0.0.0:4627|0] [0.0.0.0:4627]

Fix is in org.jboss.Main to pass the -b value through ServerConfigUtil.fixRemoteAddress(), which will return pick a non-wildcard address via InetAddress.getLocalHost().getHostName().
