Subject [jira] Commented: (DERBY-2107) Move page latching out of the lock manager
Date Thu, 07 Dec 2006 16:06:22 GMT
    [ http://issues.apache.org/jira/browse/DERBY-2107?page=comments#action_12456466 ] 
            
Daniel John Debrunner commented on DERBY-2107:
----------------------------------------------

On more, I think there has to be synchronization in isLatched() based upon previous discussions
on the list about Java's memory model.
