Agenda: 18:00 Doors open 18:20 welcome, doors closing.. 18:30 From Reactive Streams, through Virtual Threads, to Flows - Adam Warski 19:30 break 20:00 Armeria: The Microservices Framework You Haven't Tried Yet - Dominik Dorn 21:00 networking **From Reactive Streams, through Virtual Threads, to Flows** Since Java's inception, the programming model has shifted from synchronous to asynchronous, and for good reasons: improved performance, higher throughput, and lower latency. Reactive Streams greatly simplified the development of reactive systems by incorporating elements of functional programming. However, with the introduction of Virtual Threads in Java 21, Java shifts back towards a purely synchronous model, while retaining high performance. Does this render initiatives like Reactive Streams obsolete? Can we combine the benefits of Reactive Streams with the approachability of Virtual Threads, the elasticity of modern Java, and the guarantees of functional programming? And what are the tradeoffs? **About Adam Warski** Adam Warski is the co-founder of SoftwareMill and head of R&D at VirtusLab, where he primarily generates code using Java, Scala, Rust and other interesting technologies. He is actively involved in open-source projects, such as Ox, Jox, Tapir, sttp, and others. He has also been a speaker at major conferences, including JavaOne, Devoxx, GeeCON and ScalaDays. In addition to writing closed- and open-source software, he spends his free time exploring various programming-related subjects. Any ideas or insights he gains usually end up on his blog ([https://warski.org/articles](https://warski.org/articles)). **Armeria: The Microservices Framework You Haven't Tried Yet** "One port to rule them all" .. that's the promise of Armeria, the microservice framework created by the creator of Netty, Trustin Lee. Armeria has built-in support for gRPC and Thrift, automatic endpoint descriptions (OpenAPI) and works with your Spring Boot App, your legacy Tomcat project or your dropwizzard app. We'll take a look at these (and more) features in this talk. **About Dominik Dorn** Dominik Dorn is a senior software engineer in Vienna and has been running the Java Vienna Meetup since \~2009. He has extensive knowledge in the Java and Scala ecosystems. He sometimes "tweets" on [https://x.com/domdorn](https://x.com/domdorn) . You can also find him on [Linkedin](https://www.linkedin.com/in/dominik-dorn/) where he happily accepts new connections from the community. He is doing freelance software consulting, so if your company needs help, he might have some resources left for helping you.

**Was verbindet Equality, Pride, und Brompton?** Genau, für unseren nächsten Ride fahren wir entlang von fünf Artworks des Calle Libre Festivals 2026. Das diesjährige Festival steht unter dem Thema **„IN EQUALITY“**: eine Auseinandersetzung mit sozialen, kulturellen, wirtschaftlichen und gesellschaftlichen Ungleichheiten. Der Titel spielt bewusst mit zwei Bedeutungen: Ungleichheit als Realität unserer Welt und gleichzeitig in equality, die grundlegende Gleichheit, die uns als Menschen verbindet. Gemeinsam entdecken wir fünf Murals, die sich mit diesen Themen auseinandersetzen und erleben Wien dabei aus einer anderen Perspektive: auf dem Rad, in guter Gesellschaft, und mit genügend Zeit, die Kunstwerke auf uns wirken zu lassen. **Treffpunkt um 18:00 in der Brompton Junction Vienna.** Von dort starten wir gemeinsam unsere Tour durch die Stadt entlang den Calle Libre Artworks. Unterwegs werden wir natürlich bei den Artworks stoppen – Zeit für Fotos, Gespräche und vielleicht den einen oder anderen Gedanken zum Thema des Festivals. Wie immer gilt: Es ist kein Rennen!
