      Description

      I have written a test case which will demonstrate the difference between the following two scenarios:

      1. Producer sending dissimilar JMSType messages to a queue, with a client consuming all messages (no selector).
      2. Producer sending dissimilar JMSType messages to a queue, with a client consuming every other message (using selector).

      With a large enough size of test messages (for my environment about 5k), scenario 2 will fail with delivery to the consumer halted, while scenario 1 will not.

      Test Output:

      waiting for consumer to pause ... consumer: 0, producer: 0
      waiting for consumer to pause ... consumer: 200, producer: 5000
      waiting for consumer to pause ... consumer: 200, producer: 5000
      waiting for consumer to pause ... consumer: 200, producer: 5000
      waiting for consumer to pause ... consumer: 200, producer: 5000
      waiting for consumer to pause ... consumer: 200, producer: 5000
