Where is SimpleGrassTest.java?

The manual talks about SimpleTestJava here:

But I can not find this test nowhere.

I think the forester library never got published. There was quite a drama about this one. Maybe there was a compiled version like 8 years ago. Not sure why it has been added to the tutorials.

As far i know there is no grass library. But even that info might be outdated.

Looks like there are the sources included
