 Description   

Description
If you control-click a spawner that has an assigned type, serialize it using the BukkitObjectOutputStream, then deserialize it using the BukkitObjectInputStream, an error will be thrown. This could be a wider issue than just spawners but I find that it reliably gives me an error with spawners.

(See attached files for logs)

Test plugin:
1. Use 1.20.5
2. Install test plugin
3. Run "/serializationtest" with a typed spawner in your main hand
4. Error should appear in console

(See attached plugin for testing)
