Jim Newsham commented on CAMEL-4026:
------------------------------------
As far as I know, we're not using or relying on any type converters in our
application. The issue which impacts us is the fact that the
DefaultCamelContext throws an exception during startup in our application, when
deployed via webstart/jnlp.
> Camel does not work out of the box in Java webstart, due classpath scanning
> is not possible

> This is a regression. Worked fine for us in Camel 2.5.0, fails in Camel
> 2.7.1.
> Easy to reproduce. Run the following code in a webstart-deployed application:
> CamelContext context = new DefaultCamelContext();
> context.getTypeConverterRegistry();
> Which produces the following exception:
> 2011-05-26 16:52:57,550 [javawsApplicationMain] ERROR test.TestCamelContext -
> Failed
> org.apache.camel.RuntimeCamelException:
