>Environment:
i686-pc-linux-gnu
uname -r: 2.2.14-5.0
>Description:
the implementation of the static method distance
of class java.awt.geom.Point2D calls itself instead
of static method distanceSq thus causing an infinite
recursion and a stack overflow

>How-To-Repeat:
class TestPoint2D {
    public static void main(String[] args) {
	java.awt.geom.Point2D.distance( 0.0, 0.0, 1.0, 1.0);
    }
}
