title: What is "jobject thiz" in JNI and what is it used for?
body: <p>I am having a hard time finding an answer to this.  But, what is "jboject thiz" used for in JNI function calls?  For example:</p>
  
  <pre><code>jobjectArray Java_com_gnychis_awmon_Test( JNIEnv* env, jobject thiz ) {
  </code></pre>
  
  <p>I use <code>env</code> to allocate objects often, but I've never used thiz and I'm not sure what it is for.  Just for knowledge purposes.</p>
