“Could not initialize class com.sun.jna.platform.mac.MacFileUtils$FileManager” during Export on Big Sur

[processing-bot]

Created by: MarcinKonowalczyk

I'm using Processing 4.0a3 on macOS Big Sur 11.1. An error occurs when exporting an application dependent on files in the "data" folder. The following code works, but not after uncommenting the font = ... line.

PFont font;
void setup() {
  \\font = loadFont("Helvetica-12.vlw"); textFont(font,12);
  textAlign(CENTER,CENTER); fill(0);
}

void draw() {
  text("Hi",width/2,height/2);
}

Of course, 'Helvetica-12.vlw' is in ./data:

p4_loadfont_mfe.pde
data/Helvetica-12.vlw

Updated the bug title; this is an issue with JNA on Big Sur. I've already added a catch for it with this commit: 740e4b5 so this should be fixed when I have a chance to post 4.0 alpha 4.
