> According to the specification for getNormalizedComponents(int[] components, int offset,
float[] normComponents, int normOffset):
> "If the normComponents array is null, a new array will be allocated" and "an ArrayIndexOutOfBoundsException
is thrown if the normComponents array is not null and is not large enough to hold all the
color and alpha components (starting at normOffset)".
> Test listed below sets normComponents==null. 
> In this case RI does not throw an exception according to the specification while Harmony
throws.
