package io.netty.channel.unix;

This class is necessary to break the following cyclic dependency:

JNI_OnLoad
JNI Calls FindClass because RegisterNatives (used to register JNI methods) requires a class
FindClass loads the class, but static members variables of that class attempt to call a JNI method which has not
yet been registered.
java.lang.UnsatisfiedLinkError is thrown because native method has not yet been registered.

Static members which call JNI methods must not be declared in this class!
