Exception on endShape() if no calls to vertex()

Only with the JAVA2D renderer - not the others.

Code:



class Point {
  float x,y;
}

Point points[];
int numPoints = 0;

void setup() {
  size(300,300);
  points = new Point[30];
}

void draw() {
  background(255);
  beginShape(LINE_LOOP);
  for (int i = 0; i < numPoints; i++) {
    Point p = points[i];
    vertex(p.x,p.y);
  }
  endShape();
  if (mousePressed) {
    points[numPoints] = new Point();
    points[numPoints].x = mouseX;
    points[numPoints].y = mouseY;
    numPoints++;
    numPoints%=points.length;
  }
}



exception occurred (if you don't see a stack trace below this message, we've got a bug)
