Does this need to be in its own class? Can it be in AwEmbeddedTestServerImpl?

also, I think this can/should be a static method.

Relocated them into AwEmbeddedTestServerImpl and removed this class.

But when I tried to define the native method as 'private static native', jni
will complain the method is used but never defined. Weird...
