It is successfully completing the resample operation if I disable 
assertions so your fix appears to have worked.  The caveat is that if I 
don't disable assertions it throws an AssertionError during the resampling:

java.lang.AssertionError: GridGeometry2D[GeneralGridEnvelope[0..300, 
0..224, 0..0, 0..0], PARAM_MT["Affine",
   PARAMETER["num_row", 5],
   PARAMETER["num_col", 5],
   PARAMETER["elt_0_0", 20.318],
   PARAMETER["elt_0_4", -3332.314824642418],
   PARAMETER["elt_1_1", -20.318],
   PARAMETER["elt_1_4", 3983.006785884024],

Functionally I don't see anything wrong, but there may be a subtle issue 
that I haven't found yet if this assertion is failing.  Or perhaps this 
is harmless, maybe related to the Java "(NaN == NaN) = false" issue?

Thanks,
Aaron
