As per Java spec
ArrayIndexOutOfBoundsException - if bankIndices or bandOffsets is null.

If we provide bandOffsets as null, existing JDK implementation is throwing NullPointerException which is not as per spec. It should throw ArrayIndexOutOfBoundsException.

A sample demonstrating the problem:
 public static void main(String[] args) {
        try {
            WritableRaster writableRaster = Raster.createBandedRaster(
                    DataBuffer.TYPE_INT, 5, 1, 3, new int[]{0, 0}, null, new Point());
        } catch (Throwable t) {
            System.out.println(t);
        }
    }

Output:
java.lang.NullPointerException: Cannot read the array length because "bandOffsets" is null.

Code snippet causing issue:
       
        int bands = bandOffsets.length;

        if (bankIndices == null) {
            throw new
                ArrayIndexOutOfBoundsException("Bank indices array is null");
        }
        if (bandOffsets == null) {
            throw new
                ArrayIndexOutOfBoundsException("Band offsets array is null");
        }
