I was asked after the "Refactoring to #EclipseCollections" talk at dev2next 2025 whether there were any #OpenRewrite recipes for EC. My answer was "No, but it would be great if someone contributed some in OSS." Thanks Craig Motlin! 🙏 @zakhav @jitterted

I enjoyed yesterday’s chat at Code Remix Weekly by Moderne. We talked about Arconia, how it enhances the developer experience for Java and Spring Boot apps, and the key role of OpenRewrite for maintaining and growing the project. https://www.youtube.com/watch?v=v_KpRj9UXls

Stuck on old #Java versions? You’re not alone. @MBoegie shows how to overcome legacy fear, cut tech debt, & modernize with tools like #OpenRewrite — turning migrations from pain into progress.

#OpenRewrite is really neat. I used it to do some really impressive conversions. I haven't had this much fun since Jackpot refactoring in #Netbeans. I do wish it had better error messages rather than dozens of 800 line stack traces. Expect to see some contributed conversions soon…

Trotz Schnee und Eis (es war gar nicht so schlimm in #Paderborn) war der Vortrag gut besucht. Und wir konnten sogar einige neue Gesichter begrüßen. Danke @MBoegie für die vielen spannenden Einblicke in #openrewrite. 💙 #adesso SE für die Unterstützung. Und nicht vergessen im Februar geht es weiter mit "Was ist neu seit Hibernate 6?". @thjanssen123 nimmt uns mit auf eine wilde Reise durch die wichtigsten Neuigkeiten seit #Hibernate 6.

@kotlinconf I’ll be talking about @arrow_kt, our history, and future.
Evolving libraries is hard, breaking APIs even harder but sometimes essential to the success/benefit of the project/community.
#openrewrite #kotlin is looking very promising, and their team is super friendly!
