The following items are the additional fixes included in this cumulative fix:

  1. Added REST data services support which includes support for Microsoft Windows Communication Foundation (WCF) Data Services clients.
  2. Added support for creating entities without entity classes.
  3. Removed the requirement of an override ObjectGrid descriptor XML file for EntityManager API clients.
  4. Exposed an MBean to monitor and configure a thread pool that is used by evictor plug-ins, DataGrid API agents and write-behind loader plug-ins.
  5. Added template map support for the write-behind function.
  6. Enabled ObjectQuery support of super-class field and property discovery for composite keys and embedded types.
  7. Improved the ShardMBean MBean to have the correct shard type instead of INACTIVE when using template maps.
  8. Reduced the memory overhead of cache entries and queries.
  9. Added transport security support to the ogclient.jar file for eXtreme Scale clients.

  14. Eliminated timing windows for removing an entry with the write-behind function.
  15. Fixed transaction loss behavior for maps that use the write-behind function during a failover scenario.
  16. Improved the COPY_TO_BYTES CopyMode setting to support objects that use the writeReplace function.
  17. Fixed the java.lang.ClassNotFoundException and exceptions for template maps.
  18. Corrected time zone locality for entities when using attributes of type java.sql.Date and java.sql.Time.
  19. Added Coordinated Universal Time (UTC/GMT) date-time literal support for queries.
  20. Added HTTP session filter enhancements, including support for multiple partitions.
