Earlier this month we held an Adopt-a-JSR meeting with Java EE 8 Platform Specification Lead, Linda DeMichiel, and we also recorded an Adopt-a-JSR meeting in Prague with several of the Java EE Spec Leads -- JAX-RS (JSR 370), WebSocket (JSR 356) and JSON-B (JSR 367), Java EE Management (JSR 377). You can listen to the recordings and view the slides on the multimedia page:

Right now the Java EE 8 JSRs are in the early stages of development and are still forming their Expert Groups, but some of the suggestions for feedback at this early stage include providing feedback on requirements, use case development, or commenting/voting on issues in the JIRA issue tracker. Please use 'adoptajsr' tag in the JIRA issue tracker. You can find all of the links you need on the page for each JSR, for example, for JSR 366 the url is: (just change the last 3 characters of the url to the JSR number you are interested in: or see full list of the Java EE 8 JSRs, filed to date.

@Java Goes Over 200K Followers

Oracle is proud to announce the @Java twitter handle went over 200K followers in late November. Java developers are early adopters of disruptive technologies, and they took the lead on using this tool to their advantage. Tori Wieldt, Java Community Manager for the Oracle Technology Network, is the main tweeter for the account. She works to create the right balance between technical information, releases, events, and humor. “I want to include my personality on the account (humor!), but I’m not going to bore people with what I had for breakfast,” Tori told, uh, me.(1) It’s not just about followers, but about engagement. Tori loves the passion of the world-wide Java community. There’s also a nice karma that Twitter runs on Java.

Most Popular Tweets?
The most popular retweet of the last few years was from Javin Paul, a Java Architect in Mumbai, pointing to his blog explaining the difference between Method Overloading and Overriding.

Other popular tweets are the Friday Funnys:

Friday Funny: “Whats the object-oriented way to become wealthy?” A: Inheritance

Friday Funny: Traffic notice on Turkish highway: Insert your Windows installation disk: 

“So I can guess I can have it all, a passionate, world-wide community that likes to have fun!” Tori concluded.

(1) I’m a Gemini, so writing this was not as hard as you’d think. :-)

New Java Champion: Marc Hoffmann

Congratulations to the new Java Champions Marc Hoffmann!

Marc has over 10 years of Java programming experience and is the leading expert in bytecode coverage analysis. Since 2008, he has been working on Java-based railway control systems at mtrail in Berne, Switzerland. He is also the lead contributor to the JaCoCo Code Coverage engine.

Hoffmann started the EclEmma project in 2006 and authored the initial releases. EclEmma is a free Java code coverage tool for Eclipse, available under the Eclipse Public License. It brings code coverage analysis directly into the Eclipse workbench. EclEmma won the "Best Open Source Eclipse-Based Developer Tool“ - Community Award in 2008. In 2009, Hoffmann also started the JaCoCo project to create a modern code coverage backend for EclEmma and other tools. JaCoCo is now widely used as code coverage engine, including for OpenJDK 8 development. You can view his presentation, Code Coverage Revised: EclEmma on JaCoCo [PDF], from EclipseCon 2012.

Hoffmann is a well-known conference speaker on the topic of Code Coverage Analysis.  Heinz Kabutz, founder of the JCrete unconference, said, "Marc has been a big supporter of the JCrete unconference, attending all four years so far and always contributing more than he has consumed." 

Congratulations! As Java continues to grow, look for more Java Champions to join this elite group soon. The Java Champions are an exclusive group of passionate Java technology and community leaders who are community-nominated and selected under a project sponsored by Oracle. Java Champions get the opportunity to provide feedback, ideas, and direction that will help Oracle grow the Java Platform. Nominees are named and selected through a peer review process. (Current Oracle employees are not eligible.) Learn more at the Java Champions page on
