A reworked API to achieve the same result as this:
https://www.spigotmc.org/wiki/the-chat-component-api/

Needs to be friendlier than the Java impl - looks messy. Maybe a builder?

I think it would be a good idea to add a configuration option to disable/enable the /lukkit run command, and preferably, have it disabled on default.
I find it really insecure to allow any server operator to execute any Lua code, especially when a server instance runs with elevated privileges. Usually, server operators are trusted people, but what if an attacker somehow gets server operator access? The damage would be way worse than usual, as it would not be limited to the Minecraft server, but to the whole machine, or even network. An attacker with server operator access could, for instance, install a virus on the machine with some simple Java Standard Library calls.

I'm not allowed to import Lua DLL libraries, could you add that?

Summary
The utility function util.getTableFromList() doesn’t always like plugin.getServer():getOnlinePlayers().

What should happen

• getOnlinePlayers() should get a Collection of all online players.
• util.getTableFromList() should convert this data to a table.

What actually happens
At seemingly random, unpredictable intervals, without any change in code other than saving and rebooting the server, util.getTableFromList() doesn’t recognise plugin.getServer():getOnlinePlayers() as a Collection.

Outputted error (when caught)

Allowing hot reloading of functions using a file watcher would be cool. Would only be enabled for dev plugins and would need to be turned on at startup by command.

Legacy luaj is buggy.
There is a fork of luaj that is under active development: https://github.com/luaj/luaj

Builds the basics of a plugin (.yml, folder, main etc.) from something like /lukkit dev new-plugin

local testCommand = plugin.addCommand({name="test"}, function(cmd)
    local sender = cmd.getSender()
    util.runDelayed(function()
        sender:sendMessage("Test Delayed")
        return
    end, 1000)
    sender:sendMessage("Test")
end)

When i run the command the only message i get is "Test Delayed", then after a while server crashes with "The server has stopped responding!" error

Give return objects to util.runAsync(func) and util.runDelayed(func) which have an interrupt method. Maybe also an isCompleted() method?

@AL1L this one will be done before next release. Whoever gets there first wins nothing.

What should happen?
Lukkit should load

What actually happens?
Lukkit fails to load. I have tested Lukkit 1.1.3, and it loads successfully.

Give me the error!
Here you go!

A nice feature would be to load new plugins without restarting the server.

As shown by the above picture '_G.lukkit' is null as well as '_G.events'.

I know that this plugin is made for 1.79 and I am trying to use it for 1.8.8 (as you can see the plugin still loads and runs a simple lua file with out error).

I would be happy to fix this myself but sadly I am unable to figure out how to get LuaJ working in any of my projects (thus me using this plugin).
