ABSTRACTS

Java Next - From Amber to Valhalla, from Loom to Leyden, from Babylon to Panama

Java's six big projects are shaping its future and some of that is already here - just not evenly distributed. Loom has mostly delivered and is now tying up some loose ends, whereas Amber and Panama are still in the midst of finalizing their features. Valhalla is on track to preview soon but Babylon and Leyden are just starting out. Time to take a closer look at how...

  • Project Loom further improves efficient, structured concurrency
  • Project Amber makes the language more expressive and ready for today's and tomorrow's problems
  • Project Panama cuts through the isthmus separating Java from native code
  • Project Babylon extends the reach of Java to foreign programming models and hardware
  • Project Valhalla mends the rift in Java's type system and improves performance
  • Project Leyden improves Java's startup time, time to peak performance, and footprint

After this talk, you will know what to expect from Java in the next few years.

RAG in the Wild – Real-World Lessons from Modernizing Legacy Systems by Susanne Pieterse

Enterprise and government document systems hold terabytes of valuable unstructured information, yet most still rely on keyword and metadata search with little semantic context. Retrieval-Augmented Generation (RAG) promises a breakthrough, but tutorials rarely prepare you for regulated, large-scale environments.
In this talk, we'll share lessons from building a RAG stack with Spring Boot, Elasticsearch, LangChain4j, Docker, and ActiveMQ, using both Azure OpenAI and Ollama. Expect concrete insights on document chunking, enforcing access control, and keeping LLMs grounded in facts, all practical takeaways for anyone bringing RAG from demo to production.
