Method overriding

[SpigotRCE]

ProGuard doesn't exclude methods which are from a library

Hi, you'll need to provide a complete explanation of the issue you are facing and the configuration used.

As a first step, I'd check if you have setup the correct library jars rule. Without a library jar provided, Proguard will not be aware that a method is coming from a library and will treat it as first party code, optimizing it and obfuscating it as needed. See also the examples provided
