AL lib: (EE) alc_cleanup: 1 device not closed error Please Help

[MinersBlock]

I get AL lib: (EE) alc_cleanup: 1 device not closed when I try to play my minecraft mod in Eclipse. I can start the game, but when I try to create a world or play a world, it crashes. I have no errors in Eclipse either. I only get this crash if I have this typed in under my PreInit: GameRegistry.registerWorldGenerator(eventWorldGen, 0);

But if I delete that line, my mod's ores won't generate into the world . Can someone help? It would be GREATLY appreciated!

There's the issue... In the EpiCraftWorldGen class line number 43, you have a call to random.nextInt(int), in which the int < 0.

Problem fixed! Thanks larsgerrits for showing me where it was.

 

The problem was this: int posY = minY + random.nextInt(maxY - minY);

I accidentally misspelled it and put that - inbetween maxY and minY while it had to be an = sign.

I changed it to this: int posY = minY + random.nextInt(maxY = minY); now it works!

You could've easily figured that out yourself... You need to learn how to read crash reports...
