“The goal of Java 9 is to increase developer productivity while retaining Java’s key values of readability, simplicity, universality and compatibility” explains Mark Reinhold. In this video, he describes the Java 9 release that will introduce modules, addressing the complexity of class path and the monolithic JDK

JDK 8u65 and 8u66 are now available. Java SE 8u65 includes important security fixes. Oracle strongly recommends that all Java SE 8 users upgrade to this release. Java SE 8u66 is a patch-set update, including all of 8u65 plus additional features. You can download the latest JDK releases from Java SE Downloads page.
For information on new features and bug fixes included in these releases, see the following release notes:
This release also includes JDK 8u65 for ARM. See JDK for ARM Release Notes 8 Update 65 for information about this product.

Father of Java is now Liquid Robotics' chief software architect
I learned James Gosling, the creator of the Java language, is now the admiral of a fleet of water-borne drones from Mike Duigou last Thursday at the Java Hub in the JavaOne Exhibit hall. Gosling is the chief software architect for Sunnyvale-based Liquid Robotics, a 8-year-old company that uses self-propelled 7-foot-long marine robotic drones that look like surfboards to collect and transmit oceanic data for a variety of uses. Duigou told me that he was brought aboard by Gosling as Senior Software Engineer when he joined the company in 2011.
Called Wave Gliders, the drone are powered by wave energy, with the constant up-and-down motion providing energy that pulls the robots through the ocean. Duigou gave me a hand-on tour of the USS Gosling, a test Wave Glider on display in the Hub. He explained the Wave Glider is made of two parts: the surfboard-sized float that stays on the surface; and the sub that has wings and hangs 3-9 meters below the float on an umbilical tether. Because of the separation, the float experiences more wave motion than the sub. This difference allows wave energy to be harvested to for propulsion.

The Wave Glider is equipped with several computers for navigation and payload control, satellite communication systems, and ocean sensors that do things like measure weather, sea conditions, water quality and chemistry, animal life and water currents. Acoustic microphones and arrays on the Wave Glider have also been use to record passing ships and the vocalizations of whales and other mammals (an early use case of the company's technology).
The power needed to operate the sensors and computers is provided by solar panels, which are used to recharge lithium-ion batteries. Individual Wave Glider can be programmed for autonomous operation, or it can be steered by a remote pilot over the Internet. Continuous, near real time, communication is provided via satellite, cellular phone or radio links for piloting and data transmission.
All the Wave Glider computing power is Linux- and Java-based and includes a Hadoop cluster on the backend used to analyze the large data sets the devices collect, either individually or in groups. Duigou explained that the Wave Gliders can also be programmed to operate as a drone swarm. "For example, you can set up a fence around a marine protected area like Monterey Bay and give them all the goal of defending the border and reporting intruders. The robots can figure out who goes where."

Cloud Services for Developers
“Time is the greatest savings that you get from moving your development environment to the cloud,” said Oracle’s Bruno Borges, in his JavaOne presentation “Cloud Services for Developers: What’s Inside Oracle Cloud for You?” “If you have had to set up an on-premise Oracle database, or any other database, you know that it takes time to do that and you always ask yourself ‘Is these production-ready?’”
In his fast-paced, hands-on demo, Borges showed how developers can quickly get up to speed using Oracle’s pooled, shared, and elastically scalable software development platform, which gives organizations the ability to develop new applications in a quick and cost-effective way. He explained how developers can use their favorite IDE (Oracle JDeveloper, Eclipse, NetBeans) and build systems like Maven and Gradle to develop and deploy applications to the cloud.
Target different JDK Versions
Developers also have the option of choosing either Java SE 7 or 8 to leverage the particular language and JVM features their applications need. Since Oracle Java Cloud is an open platform, developers can also use any available open source or commercial Java library or framework in their applications.
Borges next walked through how to connect to Oracle Database Cloud Service to persist and manage application data as well as how to use Oracle Messaging Service to message between Java Cloud applications, on-premises applications, and Java EE and Node.js applications deployed in the Oracle Cloud. He then demonstrated how you can profile Java applications using Java SE Mission Control and Flight Recorder, in addition to the Oracle Application Performance Monitoring Cloud Service.
He also announced a new Docker Container Service that will soon be available from Oracle to help developers deploy applications into Docker containers.
In response to an audience question about Oracle Cloud scalability, Borges said that you can choose to run your application on your choice of compute size (i.e. the number of cores), and it will scale out dynamically on demand. He said they were also working on giving developers the capability to add scale programmatically using business logic, for example, in an e-commerce application that needs to scale up during the holiday season.
