> 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 );
