描述

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.

研究方向
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.
