Processing crashes

Tngabor

Hey, I've been working on a relatively simple sketch and after a few cycles of triangles being animated, processing gives me this error:

#

This is the sketch i'm running:

int TriangleNo = 5;
int gridSize = 3;

Triangle[] newTriangle = new Triangle[TriangleNo];

void setup() {
  size(700, 700);
  smooth();
  noStroke();
  colorMode(HSB, 100);

  for (int n = 0; n < newTriangle.length; n++) {
    newTriangle[n] = new Triangle();

    // get the first set of Triangles
    //newTriangle[n].display();
  }
}

void draw() {
  background(0, 0, 95);

  float grid = floor(width/gridSize);

  for (int i = 0; i < gridSize; i++) {
    for (int j = 0; j < gridSize; j++) {

      pushMatrix();
      translate(i*grid, j*grid);
      for (int n = 0; n < newTriangle.length; n++) {
        newTriangle[n].display();
      }
      popMatrix();

    } // end j
  } // end i
}

Anyone knows why this is happening?

I don't see the source for this behavior, but it crashes on OSX too. If i move the updateTriangle()-function (line 57), so that it is executed only every 100th frame, it runs for a while and i did not see crashes.
But this is still weird.

Well i'm relatively new to processing and programming so i'm not sure if it's my code that's causing the crash or something is wrong with Processing. Thanks!
