Crash when shift-clicking in my custom inventory/block

[McJty]

Hi all. I'm trying to implement a block that has a custom inventory. It has 10 ghost slots (for a crafting grid), the player inventory + hotbar as well as an internal inventory for holding items. The problem that I'm having is that Minecraft crashes (stack overflow) when I press shift-click on an item in the player inventory. I'm assuming Mc is trying to move that stack of item/item to some slot and this fails. The code can be found here:

The crash looks as follows:

  ... (and so on for a very long time)

 

Any ideas what I could be doing wrong or how I can debug this?

 

Thanks,
