[netcdf-java] Arrays with a zero in the shape array

I am working on some code that uses the array implementation from netCDF (ucar.ma2). One point I have been stumbling over is the support (or not) of arrays that have a zero in their shape array and thus have no elements.
It is possible to create such elements using the factory method, and they seem to be behave just fine. On the other hand, it is not possible to obtain such an empty array as a subsection of another array, because the Range constructor insists that 0 <= first <= last. I end up having lots of special-case checks for empty subsections because in many places in my code, empty arrays can be produced as a result for limiting cases of the input parameters.
Is there any reason why Range does not accept last < first, resulting in an empty array of the right shape? 

Konrad.
