An error occurs during reload when the main class specified in paper-plugin.yml is not a instance of JavaPlugin.

[vjh0107]

Expected behavior

It should load properly, just as it does when the server starts up

Observed/Actual behavior

it occurs when the server is reloaded.

https://pastebin.com/cn0DzfES

Steps/models to reproduce

Create an instance of JavaPlugin with PluginBootstrap, but the main class in Plugin meta should not implement Java Plugin.

My case:

1.	Provide the application’s main class in paper-plugin.yml.
2.	Instantiate the application and create a dummy JavaPlugin with the application context as a parameter to handle the plugin’s lifecycle.
3.	Everything is OK when the server’s bootstrap has finished.
4.	Reloading the server causes it to break down.

Plugin and Datapack List

I tested it in a vanilla environment.

Reloading is generally unsupported behaviour, especially for paper-plugins, so not sure if this would be worth fixing at all.

Will it be merged if I fix it and put it on PR?

No, reloading is not really supported on paper plugins. Neither is making plugins that don’t extend Java plugin.
