This week's book giveaway is in the OCAJP forum. We're giving away four copies of Programmer's Guide to Java SE 8 Oracle Certified Associate (OCA) and have Khalid A Mughal & Rolf W Rasmussen on-line! See this thread for details.
I think you are right. I did look for an errata when I bought the same book, but I never found one, then I looked at the top of the forum page
K&B Errata, but's only for SCJP5 (although some of the errors are still in SCJP6)
