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.

#PatternMatching in #Java is only applicable to objects - no longer! With JEP 455 the Open JDK project enabled primitive Types in Patterns. If you're eager for more insight, grab a ☕️ and my article about JEP 455 in the current Java Magazin 11.2024

A lot of Software Engineers and IT Managers have mixed feelings about #refactorings and #migrations. But they are omnipresent and gaining priorities in our fast-moving world. At #JCON2024 I'll turn your feelings into postiv by introducing you to #OpenRewrite. Let's meet!
