RFR: 4677581: ColorModel.getComponentSize()-wrong conditions for ArrayIndexOutOfBoundsExceptio

[Sergey Bylokhov]

The specification for `java.awt.image.ColorModel#getComponentSize(int)` states that an 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."
