Hauke Rabe created CAMEL-6459:
---------------------------------
Summary: ReplyManager holds a reference to the first calling
Bundle classloader
Key: CAMEL-6459
URL: https://issues.apache.org/jira/browse/CAMEL-6459
Project: Camel
Issue Type: Bug
Components: camel-jms
Affects Versions: 2.10.4
Environment: Apache karaf 2.3.1
Reporter: Hauke Rabe
h3. Source
The initialization of the ReplyManager is triggerd by the first processInOut
method call at the JmsProducer.
The concrete instance of the ReplyManager creates on startup an
AbstractMessageListenerContainer. The concrete listener container is generally
a DefaultMessageListenerContainer which starts a new
AsyncMessageListenerInvoker Thread.
h3. OSGI Scenario
In an osgi envrironment this AsyncMessageListenerInvoker Thread has a class
loader reference to the bundle who is triggerd by the first processInOut method
call at the JmsProducer.
Let the calling bundle (A) be another bundle as bundle (B) which contains the
JmsProducer the AsyncMessageListenerInvoker Thread holds a class loader
reference to bundle (A).
Scenario:
* Bundle (A) calls a java service of Bundle (B)
* Bundle (B) sends a jms message
* Bundle (B) receives a response of the jms message
* Bundle (B) returns the java service call to Bundle (A)
h3. Problem
At this point everything is alright but when Bundle (A) is undeployed and
another Bundle (C) calls a java service of Bundle (B) the
AsyncMessageListenerInvoker Thread has a class loader problem.
