Misconfigured CXF Endpoint url results in NPE instead of actual exception.
----------------------------------------------------------------------------
Key: CAMEL-4073
URL: https://issues.apache.org/jira/browse/CAMEL-4073
Project: Camel
Issue Type: Bug
Components: camel-cxf
Affects Versions: 2.7.2
Environment: Spring 3.0.5.RELEASE, CXF 2.3.2, Camel 2.7.2
Reporter: Sven Zethelius
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.
