Summary

Correct the specification of ArrayIndexOutOfBoundsException conditions for java.awt.image.ColorModel#getComponentSize(int)

Problem

The specification of ColorModel.getComponentSize(int) states that ArrayIndexOutOfBoundsException is thrown "if componentIdx is greater than the number of components or less than zero". The condition should actually be "if componentIdx is greater than OR EQUAL TO the number of components or less than zero."

Solution

Update the spec according to the current behavior.

Specification

java/awt/image/ColorModel.java :

-     * @throws ArrayIndexOutOfBoundsException if {@code componentIdx}
-     *         is greater than the number of components or
-     *         less than zero
+     * @throws ArrayIndexOutOfBoundsException if {@code componentIdx} is greater
+     *         than or equal to the number of components or less than zero
      * @throws NullPointerException if the number of bits array is
      *         {@code null}
