ConnectionValidator.isValid should be volatile
----------------------------------------------

                 Key: JBREM-1218
                 URL: https://jira.jboss.org/jira/browse/JBREM-1218
             Project: JBoss Remoting
          Issue Type: Bug
      Security Level: Public (Everyone can see)
    Affects Versions: 2.5.2.SP2 (Flounder), 2.2.3.SP2
            Reporter: Ron Sigal
            Assignee: Ron Sigal
             Fix For: 2.5.2.SP3 (Flounder), 2.2.3.SP3


org.jboss.remoting.ConnectionValidator's variable isValid is set in run(), which runs in one thread, and is read in ConnectionValidator.WaitOnConnectionCheckTimerTask.run(), which runs in another thread.  After ConnectionValidator.run()  sets isValid, is calls notifyAll() on a lock, which wakes up WaitOnConnectionCheckTimerTask.run(), which then looks at the value of isValid.  It's possible for the most recent value of isValid to not yet be visible to WaitOnConnectionCheckTimerTask.run().
