> Project: Camel
> Issue Type: Bug
> Components: camel-cxf

> I'm new to Camel, trying to setup the JMS CXF service based on the [http://camel.apache.org/better-jms-transport-for-cxf-webservice-using-apache-camel.html], but with our own JMS services. In the process I transposed some configuration and ended up with an NPE when CXF tried to start.
> The URL passed to jaxws:endpoint/@address="tcp://MyDomainServer1:2506,tcp://MyDomainServer1:2506". I know this wasn't what camel expected here, after debugging, but wanted to open a bug, since the actual meaningful exception is actually lost due to an NPE.
> Expected Exception. this was obtained with a debugger in CXF/camel before the NPE is thrown.

> Basically the problem is that the {{destinationEndpoint = getCamelContext().getEndpoint(camelDestinationUri);}} call fails, resulting the the FailedToCreateConsumerException first parameter to be null. Since its internally expecting the endpoint to not be null, it NPE's. Fix is most likely to make FailedToCreateConsumerException null safe. Since it principly uses the endpoint to get the URI, you could make a constructor that took the URI that you were trying to configure, instead of relying on an already created endpoint.
