Describe the Issue

This crash occurs exclusively in Creative Mode when the player throws the Francisca or Javelin and then drops the same item from their inventory, then the world auto-saves.

This results in:
java.lang.IllegalStateException: Cannot encode empty ItemStack

During saving entity NBT, indicating the thrown weapon entity is trying to save an invalid or empty ItemStack.

It does not crash in Survival Mode, likely because the thrown item consumes durability, resulting in a different ItemStack (with damage NBT) from the one being dropped.

Steps to Reproduce:

• Must be in Creative mode
• Use a Francisca or Javelin, and throw it on the ground
• Drop the item from your inventory
• Wait or trigger a save
• Crash occurs during saving entity NBT
