Methods toRGB, fromRGB, toCIEXYZ, and fromCIEXYZ of com.sun.imageio.plugins.common.BogusColorSpace class create a new array but return the original one. E.g., consider toRGB:

     public float[] toRGB(float[] colorvalue) {
        if(colorvalue.length < getNumComponents()) {
            throw new ArrayIndexOutOfBoundsException
                ("colorvalue.length < getNumComponents()");
        }

        float[] rgbvalue = new float[3];

        System.arraycopy(colorvalue, 0, rgbvalue, 0,
                         Math.min(3, getNumComponents()));

        return colorvalue;
    }

It returns colorvalue while rgbvalue should be returned instead. This may violate the specification of ColorSpace::toRGB as it states that an array of length 3 must be returned while the input array is not constrained and may have a different length. The same problem exists in other methods of this class.
