      Description

      Been working on an application that uses a lot of JMS. I noticed that reloads did not appear to happen as expected.

      DEBUG MessageSinkSource - Invoking constructor public com.fivoosh.services.activemq.MessageSinkSourceImpl(org.slf4j.Logger,com.fivoosh.services.activemq.ActiveMQConnectionSource,org.apache.tapestry5.ioc.services.PerthreadManager,com.fivoosh.services.TimeService,java.util.Map).
      DEBUG MessageSinkSource - BEGIN Analyzing com.fivoosh.services.activemq.MessageSinkSourceImpl$1
      DEBUG MessageSinkSource - END Analyzing com.fivoosh.services.activemq.MessageSinkSourceImpl$1
      DEBUG MessageSinkSource - BEGIN Analyzing com.fivoosh.services.activemq.MessageSinkSourceImpl$TextQueueSender
      DEBUG MessageSinkSource - END Analyzing com.fivoosh.services.activemq.MessageSinkSourceImpl$TextQueueSender
      DEBUG MasterMessageHandler - Processing message 'ID:Howards-Mighty-Tool.local-56885-1285896586008-3:0:9:1:1' from queue 'echo'
      Message received on thread ActiveMQ Session Task:

      { "foo" : "bar" }

      I then changed the code (it affects the logging message that starts "Processing message ....":

      DEBUG MasterMessageHandler - Implementation class com.fivoosh.services.activemq.MasterMessageHandlerImpl has changed and will be reloaded on next use.
      DEBUG MasterMessageHandler - Processing message 'ID:Howards-Mighty-Tool.local-56885-1285896586008-3:0:10:1:1' from queue 'echo'
      Message received on thread ActiveMQ Session Task:

      { "foo" : "bar" }

      Note that the message indicates the implementation class changed, but the old behavior is stuck.

      Later changes to the code and new messages sent:

      DEBUG MasterMessageHandler - Processing message 'ID:Howards-Mighty-Tool.local-56885-1285896586008-3:0:12:1:1' from queue 'echo'
      Message received on thread ActiveMQ Session Task:

      { "foo" : "baz" }

      ... do not even register that a change occured.
