1. Convenient and nice location: all sessions were in one building - there was enough time to walk between sessions, have a hallway conversation ...and get a coffee.
2. Speaking of coffee, the standard coffee was good and much better than in the hotel. And great Italian speciality coffees were served by passionate San Francisco baristas. I had my first Cortado at JavaOne.
3. Excellent presentations by core Java/Oracle engineers. They were well prepared with great content. Talking to (former) Oracle engineers / Java committers has always been my main motivation for attending JavaOne.
4. Good (great?) food, (too) good local biscuits. Always plenty of drinks and coffee.
5. Great attention to detail: useful gifts, nice stickers, JavaOne branded seat cushions, Java coasters, JavaOne signposts, badge flags and posters.
6. Good party venues: the food was good, the venues were nice, and it was easy to make conversation.
7. JavaOne was also better attended than expected.
8. Perfect organisation: from the badge to the schedule to the conference app, everything worked perfectly.

I was surprised by the quality of the conference and started asking attendees about their experiences. The answers were all positive.

The most surprising fact was that the majority of people were attending JavaOne for the first time. I asked during my presentation - more than 70% had never been to JavaOne before.

It is hard to find anything that could be improved, other than the size of the rooms. The rooms were either too big or too small. There was a lack of medium sized rooms. I also missed the evening BoF sessions, but my schedule was already packed.

In the event that my proposal is accepted - see you again in the year 2026

" J2EE to Quarkus migration can save around 50% memory for on-premise deployments, EJBs are straightforward to migrate but MDBs with two-phase commit are challenging, Change Data Capture like Debezium is an elegant solution for transaction handling, Running JFR all the time in production is a best practice for on-premise deployments, CryoStat provides visualization for JFR events in OpenShift, Quarkus binary executables work well for AWS Lambda but require managing your own runtime, Using AWS-managed Corretto runtime is advantageous for security patching, Application Load Balancer can route to both Fargate and Lambda behind the same URI, Function URL is the cheapest way to run Lambda but HTTP API Gateway provides nicer URIs, Monolithic applications are still valuable when well-structured, Modern Java with records can make JDBC more appealing than ORMs for complex queries, Cloud provider migration is less about Java code and more about mapping equivalent services, System testing should be done by deploying applications to production-like environments and testing them functionally."

1. How should I handle MDBs (Message-Driven Beans) and two-phase commits when migrating Java EE applications to Quarkus while minimizing code rewrites?
2. Is it advisable to keep Java Flight Recording (JFR) running continuously in production for capturing data when a pod crashes?
3. What are the best practices for effectively using Java Flight Recording in an OpenShift cluster environment?
4. Is deploying a Quarkus binary executable as a custom runtime for AWS Lambda better than using a container image?
5. How can a Lambda function be used to offload work from Kubernetes/locally hosted Quarkus services during peak demand?

This session is about practical, no-nonsense coding. We'll explore lean Java 21+ practices and patterns that eliminate bloat and hacks that increase productivity. We will start with structuring and organizing backend monoliths and microservices, cover testing, then move on to decoupling, abstractions, Data Oriented Programming, automation with pure Java and the impact of LLM assistants on design and code structure.

1. caching strategies for databases
2. moving fast, what to refactor, lessons learned
3. the enhanced purpose of sealed interfaces
4. Jfokus conference report
5. Digma product launch
6. BASE and 800 Java shorts

"Java well-suited for LLM inference and training, NoOps concept possible with serverless architecture, cloud services offer better automation through APIs, on-premise serverless less beneficial for regular data centers, AppWrite as backend service has pros but vendor lock-in concerns, generative AI unlikely to fully replace backend development, Quarkus offers fast cold start times for serverless functions, evolution of Java ecosystem over 8 years including shift to serverless and cloud-native development"
