The announcement that sun.misc.Unsafe will disappear in Java 9 created a huge buzz in the community and lots of people didn’t agree with the idea. While Unsafe have to go away eventually, the time is not yet and Oracle finally agreed on that.

This talk will introduce the alternatives and new features and explain how and why they will help to replace sun.misc.Unsafe. It uses basic examples to demonstrate what a Post-Apocalyptic Unsafe World will look like.
