Anyone else help?

 

You are calling random.nextInt with the max value from localContents.size().
The error "n must be positive" simply means localContents.size() is returning a number smaller than 1 (ie 0).
To fix this error simply add an if statement to check if localContents.size() is larger than 0.

Code:

        List<ItemStack> localContents = new ArrayList(this.contents);
        if ( localContent.size() > 0 ) // Check if n is positive
        for (int i = 0; i < this.maxUnique; i++) {
          do
          {
            ItemStack stack = ((ItemStack)localContents.get(random.nextInt(localContents.size()))).clone();
            if (!chest.getInventory().contains(stack.getType()))
            {
              chest.getInventory().setItem(i, stack);
              localContents.remove(stack);
            }
          } while (chest.getInventory().getItem(i) == null);
        }
