Martin Chalupa at JavaOne 2026

Martin Chalupa, a veteran Java engineer at Netflix with over eight years of experience, shares his perspective on the evolving landscape of Java development at JavaOne 2026. He reflects on how the language has become significantly more approachable over the past two decades—especially for newcomers—thanks to streamlined syntax, modern IDEs, and improved tooling. Yet he warns that the broader ecosystem’s complexity has grown exponentially, with developers now needing to master not just Java, but build tools, dependency management, and deployment pipelines. This shift, he argues, is why many young developers have gravitated toward JavaScript, though Java is now catching up with initiatives to lower the on-ramp barrier. Martin emphasizes the importance of exploring multiple technologies early in one’s career, advocating for hands-on experimentation to discover genuine passion. His session at JavaOne focuses on 'Java ahead of time' (AOT) compilation and how teams can strategically adopt emerging JDK features beyond official prescriptions. He also highlights the value of community engagement through targeted conferences like the Java Language Summit and Developer Productivity Summit, where deep technical collaboration happens. Despite not being a prolific open-source contributor, Martin actively contributes to Netflix’s open-source build tooling plugins, embodying the 'boy scout' principle of leaving things better than you found them.
