Description

The following condition seems wrong:

if(node.getX() != x0 && node.getY() != y0 && nextNode.getX() != x0
    && nextNode.getY() != y0 && node.getX() != x1 && node.getY() != y1
    && nextNode.getX() != x1 && nextNode.getY() != y1) {
   //check intersection
}

Any node with the same X or Y is skipped.
