Sorry, you are right. My bug.

A valueOf(String) or a constructor with String arg to be used for
@*Param converting could throw exceptions, also a
WebApplicationException. For WebAppExcs it is perhaps useful to map them
to the response. For all other exceptions it is IMO not useful to use
exception mappers.
