    This APAR is a cumulative fix for ObjectGrid. The resulting
    interim fix for this APAR can be applied to either V6.1.0.3 or
    V6.1.0.4.
    
    Fixes included in this cumulative fix are:
    
    1.  NullPointerException occurs when doing a DataSource lookup
    in a WebSphere client container after connecting to a remote
    ObjectGrid.
    2.  Memory leak in database update feature.
    3.  Randomize placement of shards so that when multiple
    ObjectGrids are used in an ObjectGrid configuration XML, shards
    are more evenly distributed.
    4.  Update to shutdown logic to wait for deactivate
    invocations on ShardEvents ObjectGridListeners to return
    before removing replicas from a primary shard that is stopping.
    5.  Update promotion logic when a replica is becoming primary
    to fix small timing window where the new primary thinks it
    needs to vote to rollback before it is completely available as
    a primary.
