Bug fixes

• A server appears to hang before completing stop — A server in a WebSphere Application Server or WebSphere Extended Deployment environment seems to hang for approximately three minutes before stopping.
• Catalog service cluster fails to start in WebSphere — ObjectGrid catalog services fail to start when they are configured as a cluster in one or more WebSphere application server processes.
• ConcurrentModificationException when removing attributes from HttpSession — A ConcurrentModificationException exception results if an element is removed while iterating through the enumeration result from the HttpSession.getAttributeNames method.
• DataGrid API calls server ObjectGrid multiple times — The AgentManager invokes a server ObjectGrid more than once in a partitioned environment.
• HTTP Session Manager fails in an environment that is not running WebSphere Application Server — A NoClassDefFound exception occurs when using the ObjectGrid HTTP Session Manager plug-in in an environment that is not running WebSphere Application Server web containers.
• Key failures with the AgentManager for entities — The AgentManager only accepts entities and composite keys that are schema root entites.
• Locks not held after a query is run on a client — Cache entry locks are not held after a query is run from a client when the query includes pessimistic maps.
• LockTimeoutException starting hundreds of servers or clients — Starting hundreds of catalog services clients or servers using the dynamic deployment topology in parallel with one or more entities defined might fail to start with a LockTimeoutException exception.
• NoClassDefFoundError initializing WebSphereTransactionCallback — WebSphereTransactionCallback fails to initialize on earlier versions of WebSphere Application Server.
• NullPointerException with HTTP Session Manager and static ObjectGrid topology — A NullPointerException might result when the ObjectGrid HTTP Session Manager connects to a static ObjectGrid cluster.
• ObjectGrid containers do not fail over when collocated with catalog service — ObjectGrid containers do not fail over when they are collocated in the same process as a catalog service.
• PartitionManager fails for non-Tuple and non-Root objects — The PartitionManager for entity maps fails with a ClassCastException when used with non-Tuple keys.
• Pessimistic query forUpdate might not release locks — When the Query.forUpdate option set to true, locks are not released when an exception occurs during a query over a pessimistic map.
• stopOgServer script does not have any output — In a WebSphere Application Server installation, the stopOgServer script exits without giving any feedback to the user, even if the server stops successfully.
• Synchronous replica shard fails to enter peer mode — A synchronous replica shard fails to enter peer mode and lists the reason, "A transaction threw an error while copying data from the primary."
• Unable to override default cookie name with HTTP Session Manager — Applications cannot override the default cookie name (JSESSIONID) on a per Web application basis.
