Brian, I didn't needed the stubs. At the time I wrote the document, RedHat 7.2 was not out yet ... but I tryied with it and it worked so I should just replace 7.1 by 7.2 :)
You mention JDK, watch out! You don't need any JDK installed in the machine to install Oracle, since it has it's own ... Maybe some of the problems are related to that ...? I did not install a JDK in the laptops that I had, maybe the problem lies there.
Anyway, I took most of the base of my docs from aD and adapted them to the reality I was seeing ;) so if you have some comments or updates, please let me know ... It's nice to have a good reference document, the problem is that Oracle is so complex and so big that maybe there is no way we can write the document that covers all the possible scenarios :)
Anyway, if you have any problem let me know... I will try to help you as much as I can
