Hello all! I will be sending each one of you an email. The quality of each proposal was incredible, it was the hardest DevRoom to organise so far, excluding any of the proposal was not easy, and it was one reason why we delayed this announcement. We have packed the DevRoom as much as we could possibly do, but even so we only had so much time. I wish to thank, personally and on behalf of the committee, each and anyone of you who proposed a talk, hoping to see you all at FOSDEM this year! Without further ado, this is the list of selected talks and the draft schedule for our DevRoom. 10:25 10:30 - Welcome 10:30 11:15 - State of OpenJDK 11:20 11:45 - The OpenJDK Developer Experience 11:50 11:15 - Opening the Oracle JDK 12:20 12:45 - The Z Garbage Collector - An Introduction 12:50 13:15 - Rubber 'Duke' Debugging 13:20 13:45 - MethodHandles Everywhere! 13:50 14:15 - Top Ten Metrics for Evaluating your Garbage Collector 14:20 14:45 - Graal: How to use the new JVM JIT compiler in real life 14:50 15:15 - JVM startup: why it matters to the new world order 15:20 15:45 - Class Metadata: A User Guide 15:50 16:15 - Java in a World of Containers 16:20 16:45 - Class Data Sharing - Sharing Economy in the HotSpot VM 16:50 17:15 - Hairy Security 17:20 17:45 - Hacking the JVM from Java 17:50 18:15 - G1 - Not^H^H^HNever Done! 18:20 19:00 - OpenJDK Governing Board Q&A We also have a small list of backup talks, in no particular order: AdoptOpenJDK: Enhancing OpenJDK’s “build, test, contribute” pipeline Restful Services with the Play Framework and a Security Level with JWT Shenandoah GC: What We Know In 2018 Marlin, an OpenJDK Success Story: Vector Graphics on Steroids for Java 2D and JavaFX I will be in touch with everyone directly shortly (just need some time to wrap up, but I'll start sending emails out today). Thanks again for making the Java DevRoom what it is!

Free Java DevRoom talk proposal: Marlin, an OpenJDK Success Story: Vector Graphics on Steroids for Java 2D and JavaFX

Title Marlin, an OpenJDK Success Story: Vector Graphics on Steroids for Java 2D and JavaFX Abstract The Marlin renderer is an open source pure-Java java2D anti-aliasing renderer, forked from the OpenJDK's Pisces renderer to provide a faster alternative with very good scalability to OpenJDK renderers. Since dec 2015 I contributed back the Marlin renderer to OpenJDK 9 by the successfull JEP 265. In 2016 I ported it to JavaFX in the MarlinFX project to replace the shape rasterizer in OpenJFX 9, integrated in Dec. 2016. In 2017 I improved Marlin even more: new double precision pipeline & efficient path clipping, coming to OpenJDK 10. In this session, you will learn what's new in the Marlin / MarlinFX github projects, how to use Marlin in Java 8 / 9 / 10 (including some tuning), which releases are integrated in OpenJDK / JFX 9 & 10, and get performance results on both 2D & JavaFX renderers. As the single contributor to the Marlin project, I am looking for other people to help me testing & implementing new features. Recording me on audio and/or video YES acceptable under a CC-BY-2.0 license (DEFAULT) Brief Bio Laurent Bourgès is a software engineer at the OSUG data center (CNRS) in the French Alps, working with scientists (astronomers). I learned computer programming at 5 years old (basic on zx-81) then Borland C++ on my pc computers and discovered a passion for 3D and raytracing software. After studying Physics at master level, I worked 9 years in paris in several software service companies on distributed architecture based on J2EE server clusters. I moved into Grenoble in 2009 to join the R&D software team working on observation tools for astronomers and got an academic permanent position in 2014. I have now 15 years of experience in Java programming mostly on concurrency, multi-threading & performance (optimisation, benchmarks). On my spare time, I am the author of the Marlin renderer & MarlinFX rasterizer, derived from the OpenJDK Pisces (shape) renderer. Since 2015 I am contributing to OpenJDK 9 to integrate the Marlin renderer and since 2016, to OpenJFX 9. In Oct 2017 I presented my FOSS work on the Marlin renderer at JavaOne.
