  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.
