The -Xrunjdwp:[onthrow,onuncaught] suboptions indirectly rely
on the launch suboption. If onthrow or onuncaught are specified
without a value for launch, the backend will attempt to exec a
string like "dt_socket 8000". In addition, if suspend=y (which
it does by default), the debugee will appear to hang because the
backend will suspend it before doing the exec.
