A mistake in my code, or a Java-bug?

Aron

When i close the running of my sketch, processing tells me that it could not run the sketch. Since i'm searching how to use the sound library i have no idea if it is a mistake in my code or a java-bug. Anybody an idea?

Error message:

Code:

import processing.sound.*;

Amplitude rms;
AudioIn mic;

float scale=5;
float smooth_factor=0.25;
float sum;

int x,y,r;


void settings(){
  fullScreen();
}

void setup(){
  noFill();
  noCursor();
  stroke(255);
  x=width/2;
  y=height/2;
  r=2*height/3;

  mic= new AudioIn(this,0);
  mic.play();

  rms= new Amplitude(this);
  rms.input(mic);
}

void draw(){
  background(0);

  sum+= (rms.analyze() - sum)*smooth_factor;
  float rms_scaled=sum*(height/2)*scale;
   if (rms_scaled<1){
     rms_scaled=1;
   }
  strokeWeight(rms_scaled);
  ellipse(x,y,r,r);
}

i would say library problem. processing.sound is causing problems for a lot of people.
