Two constructors of class 'java.awt.image.DataBufferUShort' contain null check of 'dataArray' after dereference it:

public DataBufferUShort(short[][] dataArray, int size) {
    super(UNTRACKABLE, TYPE_USHORT, size, dataArray.length);
    if (dataArray == null) {
        throw new NullPointerException("dataArray is null");
    }

public DataBufferUShort(short[][] dataArray, int size, int[] offsets) {
    super(UNTRACKABLE, TYPE_USHORT, size, dataArray.length, offsets);
    if (dataArray == null) {
        throw new NullPointerException("dataArray is null");
    }


As code already throw NPE when null is passed we can remove redundant {{if}} statement.
