      Description

      We have a hard time diagnozing a bug that only happens on one of our SA's machines (and only during SDM), because errai-cdi-jboss eats the exception (or at least, it doesn't relay as it should), so still don't know what the exception is.

      To reproduce the eating problem, I 've forced an NPE locally on the server side during a JAX-RS call.

      With a normal war deployment, that NPE nicely logs:

      However in Super Dev Mode with errai-cdi-jboss, that NPE does not log or show anywhere else:

      [INFO] The code server is ready at http://127.0.0.1:9876/
      [INFO] Warning! The CLI is running in a non-modular environment and cannot load commands from management extensions.
      // THERE SHOULD BE A STACKTRACE HERE TOO
      

      Without the stacktrace in the console, this is impossible to diagnose and silent errors stay hidden.
