`ObjectCollectedException` causes ScalaDebugTarget to shutdown

I don't know if this is a problem, but I have this in my logs. Maybe this should be handled gracefully, since it looks like a normal event.

(In scala-ide:a07bd6b388a3da86aebba7de3c236d7ab9b3a619) More robust against VM exceptions.

  • clearly report an actor shutting down because of an uncaught exception
using the Eclipse Error log
  • gracefully handle the common VM exceptions.

This is not exhaustive (a handful of FIXME notes are still in the codebase),
but it is a step in the right direction and fixes a number of issues I've
been seeing lately.

Fixed #1001328, Refs #1001487.

Branch: master
