[xmlblaster] NullPointerException when trying to use ConsumableQueue
Hello,
I'm trying to publish messages using ConsumableQueue like this:
TopicProperty topicProp = new TopicProperty(global);
topicProp.setMsgDistributor("ConsumableQueue,1.0");
pq.setTopicProperty(topicProp);
xmlBlaster reported an exception when receiving the message:
java.lang.NullPointerException

ConsumableQueuePlugin] processQueue: null
I did a quick trace and got rid of the exception by changing
"queue/history/maxEntriesCache" and "queue/history/maxEntries" back to
the default of 10 (I had set it to 0). I believe I had set the queue to
0 when trying to address this issue:

I'm off to test my ConsumableQueue code, just figured you may want to
know.
Thanks,
Aaron
