Description

As witnessed by gitter chat @ August 17, 2015 7:08 AM users will forget to properly handle case _ =>, we can catch matche errors there and at least include a little bit of information on which message it failed.

Research direction
Locate the EventAdapter source file in the Akka repository. The issue suggests catching match errors when users forget to handle `case =>` and including information about the failed message. Implement a try catch around the match expression, and log or return a descriptive error message. Test the behavior with a missing case.
