Project Loom, an OpenJDK project, is "intended to explore, incubate and deliver Java VM features and APIs built on top of them for the purpose of supporting easy-to-use, high-throughput lightweight concurrency and new programming models on the Java platform." These feature include Lightweight Threads, delimited continuations, and tail-call elimination. The speaker, a Project Loom team member, will describe the project in depth, in particular the gnarly details of how coroutine and continuation ...

The proliferation of heterogeneous hardware in recent years has driven us to consider that every system we program, most likely includes a mix of computing elements; each of which with different hardware characteristics enabling programmers to improve performance while reducing energy consumption. These new heterogeneous devices include multi-core CPUs, GPUs and FPGAs. This trend has been accompanied by changes in software development norms that do not necessarily favor programmers. A prime ...

In September 2017 Oracle announced that it would be migrating governance of the Java EE platform to the Eclipse Foundation, the home of MicroProfile. Two years later Jakarta EE 8 shipped, signaling the successful completion of that move. As a result, Free Java has a new home for a significant piece of the Java ecosystem. A home which is purely open source, vendor neutral, and community led. This talk will be about how the long and painful journey from Java EE to Jakarta EE unfolded. But more ...

Shenandoah GC landed in JDK12 about a year ago, giving OpenJDK another low-pause garbage collector. It has undergone substantial changes since then. Specifically we have a new barrier scheme, and have eliminated the extra forwarding pointer word per object, thus substantially reducing memory footprint. After giving a general introduction to OpenJDK GC landscape and Shenandoah GC, this talk focuses on those recent changes in Shenandoah and what's in it for you.

JDK Flight Recorder provides production time profiling and diagnostics via a compact events-based infrastructure inside the Hotspot JVM itself. JDK Mission Control is a stand-alone application that provides real-time monitoring information for Hotspot JVMs, as well as tools to read, automatically analyze and visualize flight recording data produced by JDK Flight Recorder. When this talk is presented, JMC 7.1.0 has (hopefully) been out for a little while. This presentation talks about what is new ...

The GraalVM project provides, among other options, a means to deliver Java programs as compact, self-contained, fast-startup native images. GraalVM has been moving from research to development for quite a few years now. However, it is only just beginning to be properly integrated with the latest OpenJDK releases and there is still much to be done to get it fully productized and to improve usability and performance. This talk will recount our joint experiences of trying to add new and/or improved ...
