Free Java DevRoom: Deadline Extended!
by Mario Torre 15 Dec '14

15 Dec '14

Dear Java Speakers! The deadline is approaching, but since we received a few very nice proposals but not enough to cover the DevRoom schedule, we decided to give everybody a chance and we will extend the deadline one week. We will accept talk proposals until Monday 7th December, 23:59 CET. This deadline will likely *not* be extended again, since we need to try to stay close to the 10th December deadline to allow selected speakers to book their flights and hotels! We're waiting forward for your proposals!

DevRoom Proposal: Java 9: Make Way for Modules!
by mark.reinhold＠oracle.com 09 Dec '14

09 Dec '14

Title: Java 9: Make Way for Modules! Abstract: Java 9 will introduce a standard module system to the platform in order to modularize the platform itself, improve performance and security, and simplify the development and maintenance of large applications. In this session we'll discuss how these changes will impact developers in general and those who work on the JDK in particular.

DevRoom Proposal: JCP State of the Union & Progress Report
by Mario Torre 08 Dec '14

08 Dec '14

Title: JCP State of the Union & Progress Report Abstract: The Java Community Process (JCP) program has made significant changes over the last several years in order to increase community participation in the development of Java Specification Requests (JSR) and to enable greater transparency for the community into the JSR expert groups. Reforms to the JCP through JCP.Next as well as through the Adopt-a-JSR programs have enabled this involvement from the community that is vital to the success of Java. The free and open source community now have greater opportunities for contributions and feedback . We will discuss the current state of the nation on these programs and ask for feedback and suggestions for greater participation moving forward through the ongoing JCP.Next effort, specifically JSR 364, Broadening JCP Membership and JSR 358, A major revision to the Java Community Process. How can people help out with the project, what feedback are you looking for? Comment on JCP.Next, Java EE, Java SE JSRs in development, join the JCP. Recording me on audio and/or video is acceptable under a CC-BY-2.0 license Brief Bio: Heather VanCura manages the JCP Community and Program Office. In her role she is responsible for the day-to-day nurturing, support, and leadership of the community. Heather oversees the JCP.org web site, JSR management, community building, events, marketing, communications, and growth of the membership. She is also a contributor and leader of the community driven Adopt-a-JSR programs. In 2014, Heather became Spec Lead for JSR 364, Broadening JCP Membership, as part of the ongoing JCP.Next effort. Heather is passionate about Java and developer communities. She enjoys trying new sports and fitness activities in her free time and speaking at conferences, such as FOSDEM, Devoxx, GeeCon, JFokus, Java Zone, OSCON and the JavaOne Conferences.

What Lies Beneath?: Lessons learned hacking the OpenJDK interpreter/compilers.
by Christine Flood 08 Dec '14

08 Dec '14

Title: What Lies Beneath?: Lessons learned hacking the OpenJDK interpreter/compilers. Abstract: What really happens to your Java code along the way to becoming machine code? Red Hat has been developing an almost pauseless GC for OpenJDK which requires adding read barriers to every object access. We've also developed ARM64 versions of both the server and the client compilers. This has given us quite a bit of experience with the internals of the various methods of generating machine code inside the JVM. This talk will start with a brief tour of the various levels of code generation available and then open up the floor for questions from our panel. Speakers: Andrew Haley, Andrew Dinn, Roman Kennke, and Christine H. Flood Red Hat Inc. Andrew Haley is the engineering lead of the Red Hat Java team, a member of the OpenJDK governing board, and has been a maintainer of GCJ for many years. He is also the lead of the OpenJDK AArch64 port. Andrew Dinn is a member of the Red Hat Java team and also leads the Byteman project. Roman Kennke is a long time free Java (and Software) activist, originally involved in GNU Classpath since 2004, later participated in opening OpenJDK and since then is regular contributor to several parts of OpenJDK (AWT/Swing, general class library, lately Hotspot). After finishing Diploma in 2007 he was employed by aicas, who are building a hard realtime capable Java VM. During 2009 and 2010 worked for Sun Microsystems on Java Webstart. After a short period as contractor for JP Morgan, he's now a Prinipal Software Engineer at Red Hat, where he used to work on Thermostat, the Zero and Shark port of OpenJDK, and currently on the Shenandoah GC. Christine H, Flood has 20+ years experience in programming language design and implementation. She's thrilled to be working for Red Hat on free and open software.

DevRoom Proposal: Building an open Internet of Things with Java and Eclipse IoT
by Benjamin Cabé 08 Dec '14

08 Dec '14

> We will accept talk proposals until Monday 7th December, 23:59 CET. Hopefully, today *is* Monday 7th :-) I’m sorry if yesterday (7th) was the actual deadline, I hope you will still consider my late application… Title: Building an open Internet of Things with Java and Eclipse IoT Abstract: Java is a platform of choice for many IoT applications, from building smart gateways that bridge sensors to the cloud, to device management infrastructures or home automation systems. This session provides you with concrete examples of how to build end-to-end solutions with the Eclipse IoT Java stack and in particular how to use open-source projects such as Paho, Kura, Californium and Concierge on top of OpenJDK. You should join this session if you have Java developments skills that you'd like to put to good use for your next IoT project, and if you are interested in learning more about how to use open standards like CoAP, MQTT, 6LoWPAN, … in your Java applications. Recording me on audio and/or video is: YES. CC-BY-2.0 is OK. Brief Bio: Benjamin Cabé, Internet of Things enthusiast and evangelist at the Eclipse Foundation, has years of experience in connecting things, big and small, together. He is the co-founder of the Eclipse IoT Working Group and speaker at major conferences around the world.

DevRoom Proposal: OCaml-Java - OCaml on a JVM
by forum＠x9c.fr 06 Dec '14

06 Dec '14

Title: OCaml-Java - OCaml on a a JVM Abstract: The goal of the OCaml-Java project is to allow seamless integration of OCaml and Java. Its compiler produces Java bytecode from OCaml sources, and also includes an extension to the typer in order to allow the manipulation of Java instances from OCaml programs. The Java platform is obviously a key foundation of the project, with both challenges and opportunities. Among challenges are the needs to design a memory layout and a code generator producing efficient bytecode. Among opportunities are the possibility to provide a runtime environment for OCaml that is not hindered by a global runtime lock (thus allowing shared-memory parallelism in OCaml), and the ability to use all Java libraries in OCaml projects. The talk will focus on interoperability and compiler design, with the hope to attract new testers and users. Recording me on audio and/or video: fine under a CC-BY-2.0 license Brief bio: Xavier Clerc has been working at Inria as a research engineer since 2008, but will leave Inria in early 2015 in order to found a startup. He develops the OCaml-Java project during its free time, and had the opportunity to spent several months (summer 2013) in the OCaml Labs (Cambridge University) in order to boost the project.
