null scalary type in ScalarMap


I am trying to construct a ScalarMap with a null value as one or both of the 
parameters passed in to ScalarMap(ScalarType scalar, DisplayRealType 
display_scalar). I tried commenting out the following code in the ScalarMap 

    if (scalar == null && needNonNullScalar) {
      throw new DisplayException("ScalarMap: scalar is null");
    if (display_scalar == null) {
      throw new DisplayException("ScalarMap: display_scalar is null");

However, I will get a null pointer later in that constructor if "scalar" or 
"display_scalar" are passed in as null. Is there a way to wrap a null value for 
"display_scalar" or "scalar" before it is passed in to create a ScalarMap?
