SimpleOpenNI fails with Processing 3.0

I'm getting a no such method error when trying to run simple open ni in processing 3.0a9. This happens when I call

context = new SimpleOpenNI(this);

I assume this is because PApplet has been jettisoned? Putting opengl as my renderer gave me a bit more verbose information. Not sure exactly where to file this issue, since the simpleopenni google code page is no longer active.
