NativeStaticallyReferencedJniMethods

java.lang.Object
- io.netty.channel.epoll.NativeStaticallyReferencedJniMethods

```
final class NativeStaticallyReferencedJniMethods
extends java.lang.Object
```
This class is necessary to break the following cyclic dependency:
1. JNI_OnLoad
2. JNI Calls FindClass because RegisterNatives (used to register JNI methods) requires a class
3. FindClass loads the class, but static members variables of that class attempt to call a JNI method which has not yet been registered.
4. 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!
