FirstAvailable - access and update of electedTarget is not atomic
-----------------------------------------------------------------

                 Key: JBAS-4816
                 URL: http://jira.jboss.com/jira/browse/JBAS-4816
             Project: JBoss Application Server
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: Clustering
    Affects Versions: JBossAS-4.2.1.GA, JBossAS-5.0.0.Beta2
            Reporter: Galder Zamarreno
         Assigned To: Galder Zamarreno
            Priority: Trivial

Looking at FirstAvailable load balance policy, electedTarget access/update is not synchronised, 
however, the chances of having some issues are very small. First, the proxy needs to be shared 
by various threads before the electedTarget has been set, but as electedTarget already elected 
randomly, the secondary effects of this lack of safety are none.
