* 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!
