/**
* 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().
