Is it possible to write to a PDF while using the P2D renderer?

I have a programming that is using the P2D renderer and I want to save frames to a PDF at a button press. I simply want to implement this code from the PDF examples on the processing website.

import processing.pdf.*;

boolean record;

void setup() {
  size(400, 400);
}

void draw() {
  if (record) {
    // Note that #### will be replaced with the frame number. Fancy!
    beginRecord(PDF, "frame-####.pdf");
  }

  // Draw something good here
  background(255);
  line(mouseX, mouseY, width/2, height/2);

  if (record) {
    endRecord();
    record = false;
  }
}

// Use a keypress so thousands of files aren't created
void mousePressed() {
  record = true;
}

Unfortunately, this implementation did not work for my code. It simply to produced blank PDF files. I tried simply switching the renderer to default, as it is in the example above and it was able to write a file with the image. However, my code uses PShapes and due to a bug in processing, it only looks correct using the P2D renderer, not the default. (this link shows why)

Is there a way around this? I really would like to save frames of my program to manipulate in Illustrator.
