render in java <> javascript

Hi!

When rendering this variation of the rgbcube example, using strokes in place of fills, I get what I want in java mode but the colors get changed in javascript mode. Apparently, colors are handled differently in stroke and fill methods, and it looks like a little bug is hiding there...

float xmag, ymag = 0;
float newXmag, newYmag = 0;

void setup() {
size(640, 360, P3D);
colorMode(RGB, 1,1,1,1);
}

void draw() {
background(0.6);
pushMatrix();
translate(width/2, height/2, -30);
newXmag = mouseX/float(width) * TWO_PI;
newYmag = mouseY/float(height) * TWO_PI;
float diff = xmag-newXmag;
if (abs(diff) > 0.01) {xmag -= diff/4.0; }
diff = ymag-newYmag;
if (abs(diff) > 0.01) {ymag -= diff/4.0; }

rotateX(-ymag);
rotateY(-xmag);
strokeWeight(5);
noFill();
scale(100);

beginShape(QUADS);

    stroke(0,1,1,1);    vertex(-1,1,1);
    stroke(1,1,1,1);    vertex(1,1,1);
    stroke(1,0,1,1);    vertex(1,-1,1);
    stroke(0,0,1,1);    vertex(-1,-1,1);

    stroke(1,1,1,1);    vertex(1,1,1);
    stroke(1,1,0,1);    vertex(1,1,-1);
    stroke(1,0,0,1);    vertex(1,-1,-1);
    stroke(1,0,1,1);    vertex(1,-1,1);

    stroke(1,1,0,1);    vertex(1,1,-1);
    stroke(0,1,0,1);    vertex(-1,1,-1);
    stroke(0,0,0,1);    vertex(-1,-1,-1);
    stroke(1,0,0,1);    vertex(1,-1,-1);

    stroke(0,1,0,1);    vertex(-1,1,-1);
    stroke(0,1,1,1);    vertex(-1,1,1);
    stroke(0,0,1,1);    vertex(-1,-1,1);
    stroke(0,0,0,1);    vertex(-1,-1,-1);

    stroke(0,1,0,1);    vertex(-1,1,-1);
    stroke(1,1,0,1);    vertex(1,1,-1);
    stroke(1,1,1,1);    vertex(1,1,1);
    stroke(0,1,1,1);    vertex(-1,1,1);

    stroke(0,0,0,1);    vertex(-1,-1,-1);
    stroke(1,0,0,1);    vertex(1,-1,-1);
    stroke(1,0,1,1);    vertex(1,-1,1);
    stroke(0,0,1,1);    vertex(-1,-1,1);
endShape();

popMatrix();
}
