Note that the change was reverted in Spigot build 2569. All is well, until the change is reintroduced (at some point).

I wonder why they want to make that change. You can have stacks of non-items in your inventory (blocks of ores for example). Oh well, thanks for the heads up. I will keep an eye out for the potential future change
