new SoundFile > 'target VM failed to initialize'?

Hi, I'm trying to get the sound example from www.processing.org to run but the code (copy from the site) crashed when it reaches:

sample = new SoundFile(this, nameofthefile);

nameofthefile is in my case 'song.mp3' (the original code contained 'beat.aiff')

Any ideas what the problem could be?

Thanks!
