    Hello,
    I have a problem with not seeing the full output after dumping a whole lot of lines into the console. It is for debug purpouses, thusly I cannot have Bukkit skip any lines, while it is exactly what it does. It shows only the first few lines and then the last few lines from a 320-line expected output.
    I'm assuming it is either a Bukkit functionality to decrease lag ot Java running out of output buffer.. or something? The "System.out.flush()" should empty the buffer into console, that's why I'm leaning more towards it being a Bukkit prolem. Is there any way to disable that and see the full output?

    version: 1.12.2-R0.1

    code:
    Code:
    for (long p=0L; p<320; ++p) {
      int slot = (int) (p%5); // not revellant
      long pp = p/5;         // not revellant
      int x = (int) (pp%8);  // not revellant
      pp = pp/8;             // not revellant
      int z = (int) (pp%8);  // not revellant
      int y = (int) (pp/8);  // not revellant
    
      System.out.println(p + ": " + x + " " + y + " " + z + ", " + slot);
      System.out.flush();
    }
    ouput:
    >click< (open)

    @timtower I have added it only to exclude the possibility of it being Java's output buffer overflowing. Code works exactly the same without it.

    @sebcio98 You can also write to a fike if it is for debugging

    @timtower True, that's a good alternate solution. But I would like to find a direct solution to this problem. Mostly because it's easier to debug through console with my setup, at least up to a few hundred lines, and also because I want to understand what exactly cuts those lines out and how I can affect that system.

    @sebcio98 And if you use the bukkit logger?

    @timtower I've been using different methods of printing stuff on screen, including Bukkit logger, all have the same output.
