I am getting Console Errors after playing sounds over some time with playLoop(), but i dont know if this is my mistake or if this is a Greenfoot bug? The errors look like that: Exception in thread "SoundStream:file:/C:/Users/Simon/Desktop/Greenfoot%20Projekte/SimpleGame/Projekt%2015.02/Projekt%2015.02/sounds/backgroundhighscore.mp3" java.lang.ArrayIndexOutOfBoundsException: 580 or that: Exception in thread "SoundStream:file:/C:/Users/Simon/Desktop/Greenfoot%20Projekte/SimpleGame/Projekt%2015.02/Projekt%2015.02/sounds/backgroundhighscore.mp3" java.lang.ArrayIndexOutOfBoundsException: 2305 or this: Exception in thread "SoundStream:file:/C:/Users/Simon/Desktop/Greenfoot%20Projekte/SimpleGame/Projekt%2015.02/Projekt%2015.02/sounds/backgroundhighscore.mp3" java.lang.ArrayIndexOutOfBoundsException: 2304 Does anyone knows where they come from? Is there any way to fix that, if not, does this bugs also come up on greenfoot platform or just local at my computer?

Information tags in mp3 files can often produce these type of exceptions (the first one looks very similar to it). Try re-saving the file without the tags.

Do you get the message when the sound reaches the end of it's play? I have seen that and had to edit the sound to put a bit of dead air on the end and I stopped getting the index out or bounds error.

just download audacity (it is free), open the mp3, just add a tiny bit and save as an mp3. I am not sure how the greenfoot is handling the sound buffer, but I ran into this problem in another sound library I had been using and that library was using this trick to basically turn the sound buffer into an infinite length file stream (by sensing the end and automatically sending the file pointer back to position 0 - it was very slick) but on mp3s of a certain size it would not calculate the size of the initial buffer properly.
