      Description

      I'm seeing the following exception during indexing:

      Caused by: java.lang.ArrayIndexOutOfBoundsException: 14

      This seems to be caused by the following code:

          final int level = slice[upto] & 15;
          final int newLevel = nextLevelArray[level];
          final int newSize = levelSizeArray[newLevel];
      

      this can result in "level" being a value between 0 and 14
      the array nextLevelArray is only of size 10

      i suspect the solution would be to either max the level to 10, or to add more entries to the nextLevelArray so it has 15 entries
      however, i don't know if something more is going wrong here and this is just where the exception hits from a deeper issue
