  47  *  JavaScript to Java type conversion.
  48  *
  49  *  This test passes JavaScript number values to several Java methods
  50  *  that expect arguments of various types, and verifies that the value is
  51  *  converted to the correct value and type.
  52  *
  53  *  This tests instance methods, and not static methods.
  54  *
  55  *  Running these tests successfully requires you to have
