Incorrect package name for class fatal error

[andfont]

Expected behavior

When I want to read the class package it does not give the information correctly and it is impossible to know the version, example:

public static String getBukkitVersion() {
String[] v = Bukkit.getServer().getClass().getPackage().getName().replace(".", ",").split(",")[3].split("-")[0].split("_");
return v[0].replace("v", "") + "." + v[1];
}

example error in plugin:
09:11:53 ERROR]: Error occurred while enabling PsABF v2.0.92 (Is it up to date?)
java.lang.ArrayIndexOutOfBoundsException: Index 3 out of bounds for length 3
at PsABF.jar/me.PsABF.pb.Main.getBukkitVersion(Main.java:58) ~[PsABF.jar:?]
at PsABF.jar/me.PsABF.pb.Main.onEnable(Main.java:66) ~[PsABF.jar:?]

Observed/Actual behavior

public static String getBukkitVersion() {
String[] v = Bukkit.getServer().getClass().getPackage().getName().replace(".", ",").split(",")[3].split("-")[0].split("_");
return v[0].replace("v", "") + "." + v[1];
}

Steps/models to reproduce

public static String getBukkitVersion() {
String[] v = Bukkit.getServer().getClass().getPackage().getName().replace(".", ",").split(",")[3].split("-")[0].split("_");
return v[0].replace("v", "") + "." + v[1];
}

This has not been possible anymore for a while since the cb package names no longer contain the version, see this announcement on discord from a year ago for what you can use instead.

This is false! I'm doing it from spigot without any problem but not from paper. I have it working without any problems without PAPER so it's not true. Regards
