/**

 * This test exercises the JVMTI event <code>NativeMethodBind</code>.

 * <br>It verifies that the event will be properly sent:

 * <li>for the native method called for the first time

 * <li>when the JNI RegisterNatives() is called.<p>

 * The test works as follows. The java part invokes the native method

 * <code>nativeMethod()</code> twice. At the first time that method

 * registers another native method <code>anotherNativeMethod()</code> for

 * the dummy class <code>TestedClass</code>. Registration is made through

 * the JNI RegisterNatives() call. Being invoked at the second time, the

 * nativeMethod() just returns.<br>

 * In accordance with the spec, it is expected that the NativeMethodBind

 * will be generated only one time for the nativeMethod(), and only one

 * time for the anotherNativeMethod().
