Java DSL question

[Glattfelder, Beat]

Hi Camel Riders

I am back with a simple question I found to tough to answer myself: How do I 
access the message body in a typesafe manner like in the TODO comment below? 
Obviously implementing a processor works fine, but make things harder to read.

Thanks for advising,
Beat
