Hey, right now I'm trying to make an enderchest plugin with only some slots. So I use a chestinv which I want to save in the config.yml. Here is my code: Code (Java): @EventHandler public void onInventoryOpen(PlayerInteractEvent e){ Player p = (Player) e.getPlayer(); if(e.getAction() == Action.RIGHT_CLICK_AIR || e.getAction() == Action.RIGHT_CLICK_BLOCK) { if(e.getClickedBlock().getType().equals(Material.ENDER_CHEST)) { e.setCancelled(true); ItemStack disabled = new ItemStack(Material.RED_STAINED_GLASS_PANE); ItemMeta disabledm = disabled.getItemMeta(); disabledm.setDisplayName("§cNo permissions"); ArrayList<String> lore = new ArrayList<String>(); lore.add("§7You don't have the permission to use this slot."); disabledm.setLore(lore); disabled.setItemMeta(disabledm); p.playSound(p.getLocation(), Sound.BLOCK_ENDER_CHEST_OPEN, 1, 1); Inventory inv = Bukkit.createInventory(null, 9*1, "§bEnderchest"); try { p.openInventory(stringToInventory(Config.getConfig().getString(p.getUniqueId().toString() + ".Item1"), p, "§bEnderchest")); } catch (ClassNotFoundException e1) { // TODO Auto-generated catch block e1.printStackTrace(); } catch (IOException e1) { // TODO Auto-generated catch block e1.printStackTrace(); } } } } @EventHandler public void onChestClose(InventoryCloseEvent e) { Inventory inv = e.getInventory(); Player p = (Player) e.getPlayer(); if(p.getOpenInventory().getTitle().equals("§bEnderchest")){ if(p.hasPermission("enderchest.use.1")) { String itemstring = inventoryToString(inv,1); Config.getConfig().set(p.getUniqueId().toString() + ".Item1", itemstring); Config.saveConfig(); Config.reloadConfig(); } } public static String inventoryToString(Inventory inventory, Integer Slots) { try { ByteArrayOutputStream outputStream = new ByteArrayOutputStream(); BukkitObjectOutputStream dataOutput = new BukkitObjectOutputStream(outputStream); // Write the size of the inventory dataOutput.writeInt(Slots); // Save every element in the list for (int i = 0; i < Slots; i++) { dataOutput.writeObject(inventory.getItem(i)); } // Serialize that array dataOutput.close(); return Base64Coder.encodeLines(outputStream.toByteArray()); } catch (Exception e) { throw new IllegalStateException("Unable to save item stacks.", e); } } public static Inventory stringToInventory(String data, Player p , String InventoryName) throws IOException, ClassNotFoundException { ByteArrayInputStream inputStream = new ByteArrayInputStream(Base64Coder.decodeLines(data)); BukkitObjectInputStream dataInput = new BukkitObjectInputStream(inputStream); Inventory inventory = Bukkit.getServer().createInventory(p, 9, InventoryName); // Read the serialized inventory for (int i = 0; i < inventory.getSize(); i++) { inventory.setItem(i, (ItemStack) dataInput.readObject()); } dataInput.close(); return inventory; }

I question why in gods name you are serializing inventories with base64, but in any case, the docs for OptionalDataException state that this can only happen with two causes. I believe yours if the first, where with reading the Objects, you hit a primitive. This may be how you are initially saving the inventories.
