Revision 6572

Added by Chris Jones over 12 years ago

Update getSystemMetadata() to lock(); get(); unlock() to ensure we have the latest version of system metadata from the hzSystemMetadata map. Remove the setAccessPolicy() method since it is being deprecated in the MNAuthorization API.
change insertSystemMetadata() to use a finer grained Date object on insertion. Locking of the pid happens in the subclass prior to the insert.
