NullpointerException on DeliveryChannel.send()
----------------------------------------------

                 Key: SM-1134
                 URL: https://issues.apache.org/activemq/browse/SM-1134
             Project: ServiceMix
          Issue Type: Bug
          Components: servicemix-bean
    Affects Versions: 3.2
         Environment: Mac OSX Tiger
            Reporter: Ryan Bohn
            Priority: Blocker
         Attachments: servicemix-bean-example.zip

I'm trying to send a message asynchronously from a sender to a receiver using an InOnly exchange.  When I call DeliveryChannel.send(), I get the following NullPointerException:

Sending message: Hello?
java.lang.NullPointerException
        at java.util.concurrent.ConcurrentHashMap.put(ConcurrentHashMap.java:846)
        at org.apache.servicemix.bean.BeanEndpoint$PojoChannel.send(BeanEndpoint.java:566)
        at example.Sender$1.run(Sender.java:40)
        at java.lang.Thread.run(Thread.java:613)

When I go to the line of code in the BeanEndpoint, I see the following:

requests.put(messageExchange.getExchangeId(), currentRequest.get());

Using my debugger, I noticed the value of currentRequest.get() returns null, which is not allowed in a ConcurrentHashMap (neither null keys nor null values are allowed).  the message exchange id is non-null.

I also noticed that currentRequest is only set when the component receives an exchange, which is not the case here.

Both the sender and receiver are using bean endpoints.  I have attached the project to this ticket.  You can deploy the project using maven, with the following command:

mvn install jbi:projectDeploy
