Hi Willem,
could you change the two places where you throw the exception into:
throw new IOException("Can't get the response message", ex);
instead of:
throw new IOException("Can't get the response message. Caused by: " + ex);
and
throw new IOException("Can't get the response message", exchange.getException());
instead of
throw new IOException("Can't get the response message. Caused by " + exchange.getException());
This will forward the stack trace.
After this additional change when I simply start a cxf client that forwards its message to camel jms I get the exception below. This still does not look correct. The root cause is a nullpointer exception in SimpleMessageListenerContainer.doShutdown. The attributes consumers and sessions are null. The implementation does not check this though. This results in the throw ex not being executed:
if (ex != null) {
stop(childrenStarted); <----- inside here we get the nullpointer ex
throw ex; <---- So this exception is lost
}
As we can not directly fix this I think the way to fix the problem is catching this exception in camel.impl.ServiceSupport.stop. A try catch that ignores all errors should do the trick.

> Misleading exception when a Camel-CXF Service call times out (Null InputStream is not a valid argument)
> -------------------------------------------------------------------------------------------------------
>
> Key: CAMEL-2129
> URL:
https://issues.apache.org/activemq/browse/CAMEL-2129> Project: Apache Camel
> Issue Type: Bug
> Components: camel-cxf
> Affects Versions: 2.0.0
> Reporter: Christian Schneider
> Assignee: Willem Jiang
> Fix For: 1.6.2, 2.1.0
>
>
> We use camel-cxf and camel-jms to offer CXF services over SOAP/JMS.
> When the client calls the service by using the generated stub code and a timeout occurs I get an exception "Null InputStream is not a valid argument". I would rather expect something like "Timeout calling service". Full stack trace is attached below.
> The routing config is attached below.
