Additional context
Seems like you're storing a reference to the protocol manager / accessing it before it was initialized.
Seems like you're storing a reference to the protocol manager / accessing it before it was initialized.
Same to this issue, how do I fix it?
I tried to call ProtocolLibrary#getProtocolManager in onEnable method but it not works same as onLoad, so when should I access it?
I found that there's a property called boolean initialized in class ProtocolLibrary, but it's a private property so I can't access it.

I tried to call
ProtocolLibrary#getProtocolManagerinonEnablemethod but it not works same asonLoad, so when should I access it?I found that there's a property called
boolean initializedinclass ProtocolLibrary, but it's a private property so I can't access it.
I'd already add ProtocolLib as a depend in plugin.yml and maven. Besides, I add it as a plugin in server, and it not works too.
My plugin is OnWorldPost load, and I found that ProtocolLib is OnServerLoad plugin, so there's no way to prove ProtocolLib was not loaded after my plugin loading.
When I started server, I saw Enabling ProtocolLib and never an error occurred. But when my plugin loaded and tried to call ProtocolLibrary#getProtocolManager, it throwed NullPointerException.
