Create Your Own AI-Infused Java Apps with Ease

Java Stage — 45 minutes

Generative AI has taken the world by storm over the last year, and it seems like every executive leader out there is telling us “regular” Java application developers to “add AI” to our applications. Does that mean we need to drop everything we’ve built and become data scientists (and Python developers) instead now? Fortunately, we can infuse AI models built by actual AI experts into our JAVA applications in a fairly straightforward way, thanks to some new projects out there. We promise it’s not as complicated as you might think! Thanks to the nice AI integration capabilities that the LangChain4j libraries offer, and the ease of use and superb developer experience of Quarkus, it becomes trivial to start working with AI and make your stakeholders happy :)
In this session, you’ll explore a variety of AI capabilities. We’ll start by trying out local AI models even before writing any code. Then we’ll get our hands dirty with some code and exploring LangChain4j features such as prompting and preserving state; agents and function-calling; enriching your AI model’s knowledge with your own documents using retrieval augmented generation (RAG); and discovering ways to run (and train) models locally using tools like Ollama, Jlama and/or Podman AI Lab. In addition, we’ll take a look at observability and fault tolerance of the AI integration and compile the app to a native binary. Maybe we’ll even try some new features, such as generating images, or building a full-blown Model Context Protocol (MCP) server! Read More...

Streamtoxication: How a Fluent API turns into a Tangled Mess

Java Stage — 30 minutes

Should we use streams everywhere? Certainly, using streams is often clearer and more concise than iterating a collection. But sometimes stream code requires a complex combination of collectors, folding, monads, nested flatMap operations, which makes the verdict debatable. 
In this session, we will pick several use-cases, workout the best solutions we can in both imperative and functional styles, and then argue over which is better. Of course, you'll get to vote!
If you're a Java developer, you shouldn't miss this session! You'll have fun, replenish your energy, and leave with a better idea of where streams excel, and where you should stay with old-fashioned imperative style. Read More...

Discrimination DRIFT: Reshaping the AI Divide

Women in Tech Stage — 45 minutes

As artificial intelligence (AI) continues to transform industries and societies, it also carries the risk of reinforcing and amplifying existing inequalities. In this keynote, I introduce a practical, research-informed framework designed to support the ethical and inclusive development of AI systems.  The Discrimination DRIFT framework combines the complexity of AI ethics and fairness into an accessible guide that enables professionals across disciplines to apply responsible principles throughout the AI lifecycle, from design to deployment. It also serves as a shared language for stakeholders to communicate ethical considerations clearly, supported by a simple aide-mémoire.With the high cost of AI development, addressing bias and fostering inclusivity is not only a moral imperative, but also a strategic advantage that enhances long-term profitability, trust, and sustainability. As global regulations evolve to prioritize harm prevention and fairness, and as geopolitical shifts continue to reshape regulatory landscapes, economic priorities, and global cooperation, organizations must be proactive in managing these risks.At the heart of this keynote is the introduction of the Discrimination DRIFT framework, a holistic approach that recognizes AI as a gatekeeper of opportunity, power, and capital. I will explore how Discrimination DRIFT can move society toward equity or division, depending on the choices we make today. If we focus on transparency, accountability, and inclusivity, we can shape a future where AI contributes to a more just and equitable world. Read More...

Zap the Flakes! Leveraging AI to Combat Flaky Tests with CANNIER

DevLead Stage — 45 minutes

Flakes aka tests that don’t behave deterministically, i.e. they fail sometimes and pass sometimes, are an ever recurring problem in software development. This is especially the sad reality when running end-to-end tests where a lot of components are involved. 
There are various reasons why a test can be flaky, however the impact can be as fatal as CI being loaded beyond capacity causing overly long feedback cycles or even users losing trust in CI itself. Ideally we want potential flakes to be flagged at the earliest stage of the development lifecycle, so that they do not even enter the end-to-end test suite. We want a gate that acts as a safeguard for developers, pointing out to them what kind of stability issues a test has. This reduces CI user frustration and improves trust in CI. At the same time it cuts down on unnecessary waste of CI system resources.
This talk will explore the CANNIER approach, which aims to reduce the time cost of rerunning tests. We will take a closer look at the feature set used to create training data from existing test code of the [KubeVirt](https://kubevirt.io/) project, enabling us to predict probable flakiness of a certain test with an AI model.
We will cover how a subset of the CANNIER feature set is implemented, how it is used to generate training data for an AI model, and how the model is used to analyze flakiness probability, generating actionable feedback for test authors.Attendees will gain insight on how the CANNIER approach can help them improve test reliability, ultimately enhancing overall software quality and team productivity.
