NullPointerExceptions during JMS component initialization
---------------------------------------------------------
Key: SM-963
URL: https://issues.apache.org/activemq/browse/SM-963
Project: ServiceMix
Issue Type: Bug
Components: servicemix-jms
Affects Versions: 3.2, incubation
Environment: Windows XP, JDK 1.5.0_11
Reporter: Piotr Bzdyl
Attachments: MultiplexingConsumerProcessor.java.patch
Currently org.apache.servicemix.jms.AbstractJmsProcessor.start() starts JMS
connection (and thus starts fetching messages on all already registered and all
new registered listeners) before
org.apache.servicemix.jms.multiplexing.MultiplexingConsumerProcessor
initializes its pendingMessages map in doStart() method.
It can be resolved by:
1) moving initialization of MultiplexingConsumerProcessor.pendingMessages
before consumer.setMessageListener(this); Also initializing
MultiplexingConsumerProcessor.channel field should be done before any message
arrives via listener's onMessage method.
OR
2) starting JMS connection in
org.apache.servicemix.jms.AbstractJmsProcessor.start() after whole
initialization in subclasses is done (after doStart())
I am attaching patch for the first solution.
