I found an errata in the OCP Java SE11 Programmer I Study Guide by Jeanne Boyarsky and Scott Selikoff.
On pages 471 and 473, they are referring to a module "zoo.animal.staff" in a few places. The correct module name should be "zoo.staff", as described in earlier pages.

I had already checked that list before I posted. It's not listed there.
I'm now up to to "repurposing" of this chapter for our 816 book. I've fixed it there. I also fixed it in the github repo. Your name is now in a commit comment (click the commit to expand details to see it)
