The spec ( http://java.sun.com/javase/6/docs/api/javax/swing/border/TitledBorder.html#getBaseline(java.awt.Component,%20int,%20int) ) says:

Throws:
    IllegalArgumentException - if width or height is < 0

For example, the following lines of code will throw nothing:

    new TitledBorder("123").getBaseline( new Button(), -1, 0 );
    new TitledBorder("123").getBaseline( new Component() {}, Integer.MIN_VALUE, 0 );

N/A

TitledBrder should do the same as its super class does:

        if (width < 0 || height < 0) {
            throw new IllegalArgumentException(
                    "Width and height must be >= 0");
        }
