com.jacob.com.SafeArray
This creates an array wrapper around Variant objects(?). This supports 1, 2 and n-dimensional arrays. It exists in this form because n-dimensional arrays were a later addition.


      // wrap the script control in a variant
      Variant v = new Variant(sControl);


      // create a safe array of type dispatch
      SafeArray sa = new SafeArray(Variant.VariantDispatch, 1);


      // put the variant in the array
      sa.setVariant(0, v);


      // take it back out
      Variant v2 = sa.getVariant(0);
      Dispatch d = v2.toDispatch();


      // make sure you can call eval on it
      result = Dispatch.call(d, "Eval", scriptCommand);
      assertTrue(result.toString().equals("6"));
