  45  *  JavaScript to Java type conversion.
  46  *
  47  *  This test passes JavaScript number values to several Java methods
  48  *  that expect arguments of various types, and verifies that the value is
  49  *  converted to the correct value and type.
  50  *
  51  *  This tests instance methods, and not static methods.
  52  *
  53  *  Running these tests successfully requires you to have
