Camel routes using XSTREAM can not be used

Hi,

In the attached test case, we have a simple route:

       public void configure() throws Exception {
           from("activemq:a")
           // Removing xstream will allow the camel ide to work, I have tested with
           //  .marshall().serialization() and it works fine, problem seems to be with xstream
           .marshal().xstream()
           .to("activemq:b");
       }

When using XSTREAM, we can not explore this route in FuseIDE in any manner. Simply clicking on Camel Context causes errors as does start tracing and edit routes. The underlying problem seems to be a missing class. (see stack trace below). I also attached a screen shot with some of the other errors received when trying to start trace / edit route. This same route works just fine when using "serialization".

As part of this jira, if there is any way to improve the error handling? Users simply receive "Editor could not be initialized with a one line detail, java null pointer exception. Not particularly user friendly especially hard if one doesn't know about the Error Log.

Steps run test:
============

mvn clean install
mvn exec:java
Using JMX explore connect to the mvn exec:java process.
Click on things.

Error from simply clicking on Camel Context"
