Conference

JavaLand 2023 is a three-day on-site conference. It will run from March 15 through March 17, 2022. Talks are scheduled for the first two days; I assume that the third day will be a training day.

It’s Germany’s biggest Java conference and had 2.100 visitors in 2019. The German Oracle User Group, the Association of the German Java User Groups, and the German publisher Heise Medien organize this conference.

I spoke at JavaLand in 2021 about how Java developers should build front-ends. In 2022, I gave talks about (Google’s cross-platform UI framework Flutter and data versions in Java).

Talk

My German talk “Wann lohnt sich Native Java mit GraalVM für mich?” (“When Is Native Java With GraalVM Worthwhile for Me?”) will be on Wednesday, March 22, 2023, at 14:00 local time. The talks don’t have a URL of their own. Instead, they are overlay windows. So please use this link to search for my name and then click on the “magnifier with plus” icon to see the abstract.

Abstract

German

Java dominiert Enterprise-Anwendungen. Aber in der Cloud ist Java oft teurer als Konkurrenten wie JavaScript, Python oder Go. Native Java durch die GraalVM AOT (Ahead-of-Time) Compilation macht Java billiger: Die entstehenden, nativen Java-Anwendungen starten viel schneller und benötigen weniger Speicher. Aber das klappt nicht für alle Java-Anwendungen, macht Entwicklung & Betrieb komplizierter und ist auch noch recht neu.

Wann lohnt sich nun Native Java für mich? Meist beleuchten Vorträge zu diesem Thema entweder nur die Vorteile oder bloß die Nachteile und geben “Kommt darauf an” als Empfehlung.

Mein Vortrag dagegen beleuchtet sowohl Vorteile als auch Nachteile von Native Java. Ich erkläre, wie Native Java funktioniert und wann Sie es nicht einsetzen können. Und ich sage Ihnen konkret, wann sich Native Java für Sie lohnt – und wann nicht.

English

Java dominates enterprise applications. But in the cloud, Java is often more expensive than competitors like JavaScript, Python, or Go. Native Java with the GraalVM AOT (Ahead-of-Time) compilation makes Java cheaper: The resulting native Java applications start much faster and use less memory. But that doesn’t work for all Java applications, makes development & operation more complicated, and is also quite new.

When is native Java worthwhile for me? Usually talks on this topic either only highlight the advantages or only the disadvantages and give “It depends” as a recommendation.

My presentation, on the other hand, examines both the advantages and disadvantages of native Java. I explain how native Java works and when you can’t use it. And I’ll tell you specifically when native Java is worth it for you - and when not.

Who Made Me the Expert?

I’ve been a Java developer for 23 years and still write code every day. I’m a Java news reporter for InfoQ, so I know what’s going on in the Java world. I was the editor of a six-part InfoQ article series on native Java and also wrote about it for InfoQ (here, here, and here).

I’m not selling books or training courses, and I’m not a developer advocate. I share my experiences and my knowledge so you can do get better projects faster!
