Thomas Wuerthinger is a Vice President at Oracle Labs leading programming language implementation teams for languages including Java, JavaScript, Python, and WebAssembly. He is the architect of the Graal compiler and the Truffle self-optimizing runtime system. Previously, he worked on the Crankshaft optimizing compiler of V8 at Google, and the Maxine research virtual machine at Sun Microsystems. He received a PhD degree from JKU Linz for his research about dynamic code evolution.
GraalVM Native Image allows for ahead-of-time compilation of Java applications into native binaries. The advantages are instant startup, better warmup, lower memory footprint and improved security. This talk will showcase each of those advantages for an example Java server application. Also, it will demonstrate some of the new tooling available for your application when deployed in such a setup. This includes Linux perf as well as other native binary inspection tools that provide accurate insights into your running application. The talk will also cover challenges of creating native images and recommendations based on what criteria to choose ahead-of-time or just-in-time compilation for your Java application.
Over a decade ago, we had a bold research idea: to create a universal runtime for executing many different managed languages. This sparked the creation of the GraalVM project. Starting small and facing resource constraints, the team was forced to innovate, embarking on a long and winding road that ultimately led to the development of a widely deployed product. In this talk, we’ll explore the key lessons learned, from setbacks and failures to surprising moments of success—demonstrating how unexpected circumstances played a critical role in shaping our journey
