Why not simply create a Fiter that has a try/catch block in the doHandle()
method? The try block would simply pass control to the next Restlet, and if
somewhere downstream a Handler throws a particular unchecked exception, the
filter will do the proper handling. This of course assumes a downstream restlet
isn't arbitrarily catching unexpected Throwables (which probably isn't a good
idea anyway).
