Hello!

I am relatively new to Processing, and I am trying to connect Processing and Arduino with Firmata.
I am using the 32 bit version of Processing and Java (a previous problem with Firmata forced me to).

Now, when I try to run one of the 3 examples given with the library, such as the arduino_pwm example, I get this error:
illegalAccessError: tried to access class processing.core.PApplet$RegisteredMethods from class cc.arduino.Arduino$SerialProxy

Stable Library
=========================================
Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7
Exception in thread "Animation Thread" java.lang.IllegalAccessError: tried to access class processing.core.PApplet$RegisteredMethods from class cc.arduino.Arduino$SerialProxy

    at processing.core.PApplet.run(PApplet.java:2006)
    at java.lang.Thread.run(Thread.java:662)

Here is the code:

1. import processing.serial.*;
   
   import cc.arduino.*;
   
   Arduino arduino;
   
   void setup() {
     size(512, 200);
     arduino = new Arduino(this, Arduino.list()[0], 57600);
   }
   
   void draw() {
     background(constrain(mouseX / 2, 0, 255));
     arduino.analogWrite(9, constrain(mouseX / 2, 0, 255));
     arduino.analogWrite(11, constrain(255 - mouseX / 2, 0, 255));
   }

Apparently the error is situated on this line: arduino = new Arduino(this, Arduino.list()[0], 57600);

Any idea?
Thanks!
