JavaLand 2026: Agenda - DOAG JavaLand 2026: Agenda

🧙 Gleich Java Panel: Zukunft von Java. Meine These: Die Plattform ist schneller als ihr Ökosystem und Migration ist die eigentliche Arbeit, über die wir zu wenig reden.

14:00, Bellevue, @javaland.bsky.social. #Javaland #Java

More action, more overview - From 4k to 1M Threads SpeakerDeck

Talk ist durch. Virtual Threads, Structured Concurrency, OpenRewrite-Analyse, Moderne CLI - und die Fragen danach haben gezeigt: Der Migrationspfad ist das, was die Leute wirklich beschäftigt. #JavaLand #Java

Auf dem Weg zu meiner fünften @javaland.bsky.social. Die neue Java Concurrency API ist einfach, aber Teams fehlt der Migrationsplan. Darüber sprechen wir diese Woche. #Java

Today is a great day to verify you don't get yourself locked out of any 2FA-secured accounts when losing your phone. Print out back-up codes, set up fallback keys, etc. It takes just a few moments and can save you massive headaches later on.

Java 25 removes the SecurityManager, replaces ZipError, and more. Don't panic.

@openrewrite.github.io helps you get rid of the hurdles to focus on more awesome stuff - like pattern matching or concurrency.

One Maven command migrates your entire codebase safely.
