jiridanek commented on pull request #238: PROTON-1675 [cpp] Attempt to listen 
on invalid URL will not throw exception
URL: https://github.com/apache/qpid-proton/pull/238
 
 
   Calling listen() with invalid address is not supposed to throw a C++ 
exception, it is supposed end up calling the `on_error` callback. So let's 
remove the try catch blocks from the test, since there aren't any expected 
exceptions here.
