Slave broker acquires lock file when Master is still alive (shared file system master/slave
setup)
--------------------------------------------------------------------------------------------------

                 Key: AMQ-3273
                 URL: https://issues.apache.org/jira/browse/AMQ-3273
             Project: ActiveMQ
          Issue Type: Bug
          Components: Message Store
    Affects Versions: 5.5.0
         Environment: Windows 7, Windows Server 2008 
            Reporter: Dariusz Szablinski
            Priority: Critical
             Fix For: 5.6.0, 5.5.0


The change introduced in AMQ-3237 has triggered issue with LockFile.lock() on Win7 and Win2k8.
See comments to the JRE issue http://bugs.sun.com/view_bug.do?bug_id=6628575 (bottom of the
page).  

Suggested solution is to use this construction instead:
fc.lock( 0, Math.max( 1, fc.size() ), false );
