I receive the following error shortly after I call a C++
function from a Java class via a 'native' method. I have
a diagnostic 'printf' at the beginning of the C++ function
that successfully runs, but during my
'(*a_pJNIEnv).GetStringUTFChars( )' calls that follow, the
crash occurs.

I had an idea about something along the lines of "recursive, parametric object
definition" so I decided to write the below code for fun. If your not familiar
with parametric math, this class basically creates an n sided object using
cosine and sine. The limit as n --> infinity, the more "circleish" this object
gets. The input is as follows:

java RCircle [radius] [points to generate]
ex:
java RCircle 2 4

*/
// begin
import java.text.NumberFormat;

public class RCircle {
    private static RCircle first;
    private static double radius;
    private static double inc;

    private boolean isFirst;
    private double x;
    private double y;
    private RCircle next;

    public RCircle (double radius, double inc) {
        first = this;
        this.radius = radius;
        this.inc = inc;

        isFirst = true;
        x = radius;
        y = 0.0;
        next = new RCircle (inc);
    }

    private RCircle (double time) {
        x = (double) (radius * Math.cos(time));
        y = (double) (radius * Math.sin(time));
        if (about(x, radius, .0001) && about(y, 0.0, .0001))
            next = first;
        else
            next = new RCircle (time + inc);
    }

    public RCircle getNext() {
        return next;
    }

    public double getX() {
        return x;
    }

    public double getY() {
        return y;
    }

    public boolean isFirst() {
        return isFirst;
    }

    public boolean about(double a, double b, double r) {
        return (a + r > b && a - r < b);
    }

    public static void main(String[] args) {
        NumberFormat nf = NumberFormat.getInstance();
        nf.setMaximumFractionDigits(3);

        RCircle r5 = new RCircle (
                                  Double.parseDouble(args[0]),
                                  2 * Math.PI / Double.parseDouble(args[1])
        ).getNext();

        while (r5.isFirst() != true) {
            System.out.println(
