Hi,
I'm getting this exception in my code:
Exception in thread "Thread-3" java.lang.NullPointerException
at processing.core.PLine.drawLine_smooth(PLine.java:1062)
and I narrowed it down to this phrase:

   println("a");
   oot.rect(0,0,10,10);  //draw the rect box
   println("b");

a prints, b does not. The program stalls.

Here is part of the code that leads up to this:
   PGraphics oot= createGraphics(int(cWidth*dpi),int(cHeight*dpi),P2D);
   oot.beginDraw();
   oot.background(0,0,0);
   oot.smooth();
   oot.fill(255);
   oot.stroke(0);
   oot.pushMatrix();
   oot.scale(scal);              //scale down
   oot.strokeWeight(1/scal);
   println("a");
   oot.rect(0,0,10,10);  //draw the rect box
   println("b");

This problem began after I updated my code for 118 (from 103 or so). I switched oot from PGraphics2 to PGraphics because it seems there is no PGraphics2 any more as well as some other stuff.
