  It caused a regression:

  For some reason, a couple of extra jvm event callbacks appeared:

  There must be something in the noncore library that registers callbacks in
addition to what the test was expecting.  But then I'm not sure why they
wouldn't also be registered if the full non-partitioned libgcj was in use.
Until I can figure this out, I guess I don't understand how dependencies work
in java well enough, so patch withdrawn/on hold.
