Maybe you're not waiting for the right thing. Have you tried to wait for the realization of the drawable?

I have to clarify the initialization sequence in the documentation. When the frame handler calls canvas.init(), it will initialize the canvas only if it hasn't already been done. I don't use a frame handler in my game, that's why I always call canvas.init(). Java3D Canvas3D is very different, it's closer to an AWT canvas than something OpenGL related whereas it doesn't make sense to realize a non visible onscreen drawable without visible top level container.

isRealized() doesn't throw a NullPointerException:

I have to throw Guava out of our engine, switch to Java 1.8 and fix a very few issues before releasing the version 1.0.

Yes, the "eviction" takes some time, be patient.
