      Calling getTileEntities on the chunk returned by ChunkUnloadEvent throws an error.

      It can be produced by the following code:

          @Override
          public void onEnable() {
              Bukkit.getPluginManager().registerEvents(this, this);
          }
      
          @EventHandler
          public void onChunkUnload(ChunkUnloadEvent e) {
              for (org.bukkit.block.BlockState state : e.getChunk().getTileEntities()) {
                  //weeeeeee
              }
          }
      

      This effectively renders the getTileEntities method useless.
      I have not tested if it affects block related functions.
