It verifies that the event will be properly sent: *
  • for the native method called for the first time *
  • when the JNI RegisterNatives() is called.

    * The test works as follows. The java part invokes the native method * nativeMethod() twice. At the first time that method * registers another native method anotherNativeMethod() for * the dummy class TestedClass. Registration is made through * the JNI RegisterNatives() call. Being invoked at the second time, the * nativeMethod() just returns.
