Pat Fox updated AMQ-3746:
-------------------------
Description:
Non Durable Topic subscription with prefetch=0, MessageConsumer.receivenowait()
(or MessageConsumer.receive(timeout) hangs indefinitely.
I get the following thread dump
{code}
"main" prio=5 tid=7f996d000000 nid=0x105bc3000 in Object.wait() [105bc1000]
java.lang.Thread.State: WAITING (on object monitor)
at java.lang.Object.wait(Native Method)
- waiting on <7f39f1b30> (a java.lang.Object)
at java.lang.Object.wait(Object.java:485)
at
org.apache.activemq.SimplePriorityMessageDispatchChannel.dequeue(SimplePriorityMessageDispatchChannel.java:87)
- locked <7f39f1b30> (a java.lang.Object)
at
org.apache.activemq.ActiveMQMessageConsumer.dequeue(ActiveMQMessageConsumer.java:468)
at
org.apache.activemq.ActiveMQMessageConsumer.receiveNoWait(ActiveMQMessageConsumer.java:621)
at
org.apache.activemq.usecases.TopicSubscriptionZeroPrefetchTest.testTopicConsumerPrefetchZero(TopicSubscriptionZeroPrefetchTest.java:71)
{code}
It seems the TopicSubscription does not support "pullMessage".
This only appears to impact Non Durable Topic Subscriptions. Durable Topic
Subscriptions with prefetch=0 do *NOT* exhibit this behavior.
