主题:Truffle and Graal: Building fast interpreters on top of the JVM
I will present how to build interpreters using the Truffle framework. Existing virtual machines usually have the JIT compiler deeply integrated into the virtual machine and the run-time. The Java Truffle framework and Graal compiler, however, separate this two concerns: A language implementer writes an Abstract Syntax Tree (AST) interpreter using Truffle. Upon execution, the framework will let Graal compile its hot execution paths by assuming the structure of the AST interpreter and performing related optimizations. The result is fast code, portability over platforms, and language interoperability.

主题:Java 8: Create The Future
With nine million developers across the globe, Java is the most popular development platform in the world today. With the launch of Java 8 powerful new features will be added across the entire platform: language syntax, class libraries and virtual machine.This session will explain what the main new features are and how they benefit developers. We’ll start with Java SE 8, explaining the basics of Lambda expressions, streams and functions as well as things like the expanded use of annotations, the new date and time API and extension methods. Next we’ll look at Java ME 8 and how new profiles and APIs are targeted at the rapidly expanding Internet of Things development. Finally we’ll take a look at how NetBeans 8 supports all the features discussed in the rest of the presentation and makes developer’s lives easier.
