Other interesting topics / information from the Java Keynote (among others):
Georges Saab, Vice President of Development at Oracle, promised that the JDK will be optimized for working with Docker. Unfortunately, there was no information given about when and how this will happen. Afterwards, Mark Reinhold entered the stage to talk about the new features of Java 9. Then he talked about the details of Project Jigsaw and the new JShell.
Java EE 8 will be released end of 2017.
The Intel Keynote with the topic "Enabling a Smart and Connected World with Java" was presented by Michael Green (VP Intel). The most interesting part was that Java will run on Intel Joule. He also welcomed Benjamin Wolff from CERN, Nandini Ramani (Twitter) and Reynold Xing (Project Apache Spark) who talked about how Java enables their companies to be successful. For example the Accelerator Control Center (CERN) runs on Java since mid 90's.
During the Visionary Keynote Dr. Anita Sengupta (@Doctor_Astro) talked about Mars exploration, Curiosity rover, "7 minutes of terror" when landing, and lots of other extremely interesting considerations and challenges in her work.
