Claus Ibsen resolved CAMEL-3515.
--------------------------------

       Resolution: Fixed
    Fix Version/s:     (was: 3.0.0)

I will mark this as resolved. We can later create a ticket if we want to consider supporting being able to specify default values for parameters in the methodName option.

> We need this new feature documented
> http://camel.apache.org/bean
> And we need this option on the these
> - MethodCallExpression
> - BeanExpression
> And we need unit tests which uses the method call expression in
> - camel-core
> - camel-spring
> Also the String -> Class converter should use the ClassResolver API from CamelContext. This ensure it runs in OSGi, JBoss, J2EE etc.
> What you do is just add Exchange as the 2nd parameter and Camel provides it to you
> {code}
