Known Issues and Considerations


JMS API open issues, unsupported features, and considerations

  • GS-2167 – Durable subscribers are currently not supported. Trying to invoke the Session.createDurableSubscriber method or the Session.unsubscribe method throws a JMSException.
  • GS-2168 – When consuming messages from a Queue, and a session recovery takes place, the JMSRedelivered header of the recovered messages is not set. This problem does not occur with Topic recovered messages. Message recovery takes place in the following scenarios:

    • Transaction rollback.
    • The Session.recover method is invoked.
    • In case of space failover (for more details, see the JMS failover section).
  • GS-2169 – Message Selectors are currently not supported. Creating a MessageConsumer with a selector does not effect the message consumption. Note: Since the JMS message is also a space entry, you can use the space template matching and querying features.

  • GS-2170 – Message priority is currently not supported. Currently, all message are have the same priority: Message.DEFAULT_PRIORITY. When setting the priority of a message, the priority value is set correctly in the message, but the JMS layer does not take it in consideration. As a result, when messages are redelivered, even if a message with higher priority arrives, it is not delivered before other messages.

  • GS-2171 – JMS sessions support only a single MessageConsumer. Trying to create a consumer for a session that already has a consumer throws a JMSException.

  • GS-2173 – JMS does not support StreamMessage. Using this message type will probably cause errors, and therefore is not recommended. A working implementation of StreamMessage is planned for future releases.

  • GS-2213 – JMS does not support message delivery threshold. A JMS provider might implement a message delivery threshold that prevents a message from being redelivered (due to session recovery) more times than that threshold number. When that number is passed, the message is sent to a dead letter queue. Currently, this feature is not supported.

  • GS-3314 – In cluster environment, custom JMS destinations that are specified in the properties file are not bound to the RMI registry. For example, you may bind a JMS Queue by setting the property space-config.jms.administrated-destinations.queues.queue-names=gs.Queue1. You should expect to find it in the RMI registry as GigaSpaces;ContainerName;spaceName;jms;destinations;gs.Queue1, but it will be missing. Workaround:

  1. Extract the file: DefaultConfig_ClusteredJMS.xml from xap-datagrid.jar\config to the JS_HOME\config.
  2. Edit DefaultConfig_ClusteredJMS.xml to contain the required Queue:
<queues>
    <queue-names>MyQueue,TempQueue,gs.Queue1</queue-names>
</queues>
  1. Restart the cluster. This should make the required queue available in the RMI registry of all spaces in the cluster.
  • GS-3478 – JMS does not support destination partitioning. Currently, all messages of a JMS destination are routed to the same partition. The partition where the messages go is resolved according to the index field of the message which, currently, is the destination name.
