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.

Teaching @openrewrite.github.io, my favorite moment is watching devs write their first custom recipes, realize they can query any codebase like a database, then immediately plan to refactor their entire monolith.
Today's lab: From "what's a visitor pattern?" to "I can transform 1M lines" with tests

Will AI take my job? I don't think so, and in my second talk at @devoxx.com yesterday, I explained why. The slides are in the companion app and also at speakerdeck.com/mthmulders/w.... Enjoy!

Bye @devoxx.com ! Amazing week of community & content. Great talks with @mthmulders.bsky.social, @mauricenaftalin.bsky.social & Philippe at @oracleace.bsky.social meetup. Learned tons from Geoffrey on Open Core & advocacy. Thanks to all who joined my OpenRewrite session on digital sovereignty!

Tomorrow at #JCON2025, @mboegie.dev tackles the tech debt trap: too many tools, too many legacy choices. He shows how to consolidate your stack & migrate seamlessly with #OpenRewrite. Join his session!

More on #MigrationEngineering in his #JAVAPRO article → javapro.io/2025/05/1...

Tomorrow starts @jcon.one in Cologne where I give two #Mentoring Sessions as part of the Mentoring Hub. One about #MigrationEngineering and one about becoming a #Speaker. Register now (link 👇) or meet me at the @moderneai.bsky.social booth.
