This week's book giveaway is in the OCAJP 8 forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide and have Edward Finegan & Robert Liguori on-line! See this thread for details.
The spec not only doesnt define the return value explicitly, the reference to another book is only made in small font found under the bottom of the page. I dont understand why such an important information is treated with such an indifferent attitude.
