/**

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

 * <br>It verifies that the event will not be sent when the native

 * method is unbound.<p>

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

 * <code>registerNative()</code> which registers native method

 * <code>nativeMethod()</code> for the dummy class <code>TestedClass</code>

 * and then unregisters it. Registration/unregistration is made through

 * the JNI RegisterNatives()/UnregisterNatives() calls.<br>

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

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