If online, owner is always a viewer. If offline, they are never a viewer. There's no reason to count them - keeps inventory permanently cached while online if opened, even if not in use.
Because there is no option to create a `remapped-mojang` artifact for 1.16.5 and the whole point of the scripts is to save me time, 1.16.5 support is being removed earlier than usual.
Also fixes issues with NMS-based shulker collision check.
Closes#36
With the recent uptick in requests for support by people running 1.12 who have recently updated past Java 9, I revisited the supported versions.
First, the "modern" versions: 1.15 is run by 2.9% of servers, 1.16.3 by 5%. Since all of these versions are supported to ease the transition of updating servers and servers have updated, there's no real reason to keep them around. It's a lot easier if you can update a plugin and just have it work on both versions rather than push all the plugin updates to master with the server update, but none of these versions have any reason for long-term support.
Regarding heavily outdated server software: As of the time of writing, 1.8 and 1.12 have market shares of 8.6% and 8.5% of servers respectively.
Regarding 1.8: 1.8 support is already a bit wonky - with the changes made to inventory names, it's not (easily) possible to bridge the gap, and future changes will make that more and more difficult. People use 1.8 because they disliked the 1.9 combat changes, but there are plugins that fully rework combat to how it used to be. I have yet to hear a compelling argument that cannot be resolved with plugins. In the interest of my own sanity (handling and backporting the inventory name change in particular was a real humdinger) I will no longer be backporting changes to 1.8.
Regarding 1.12: I am honestly not sure why people are not updating. I get it, 1.13 and the flattening was a rough transition, but pretty much every developer active at the time bridged the gap. If your server is heavily dependent on some software only available at that time, you can live with other software available at that time. At the time of 1.12's release, Java 9 was not released. Either update your server, downgrade Java, or fork OpenInv and backport Java 9 support yourself.
