Are your applications still running on Java 8 or even older, unsupported versions? Or maybe you've already made the move to Java 11? Thinking about switching your application to run on Java 17 and not sure where to start? There is a lot to think about when it comes to planning a Java migration, but there are tools and strategies that can help!

Java language has been evolving at a fast pace with the six-month release cadence and preview features. These language features will be discussed in detail in the talk "Brewing Patterns in Java - An Informal Primer."

This talk explains the different working mechanisms of the Java Spring framework and how to integrate it in cloud, model view controller and other frameworks.

Last year, the AdoptOpenJDK project moved to the Eclipse Foundation under its new name Eclipse Adoptium. Meet the Eclipse Adoptium Working Group members to get the latest news regarding itself and the related Eclipse Temurin (OpenJDK binaries), AQAvit (Quality Assurance) and Adoptium Marketplace (multi-vendor binaries) projects.

The Eclipse OSGi Feature Service is a new specification that makes is easy to define and re-use OSGi-based components and applications. The Eclipse OSGi Specification Project is currently working on a Feature Launcher specification that builds this out to create running systems from Feature definitions. In this talk we'll look at an implementation of the new launcher in action.
Then we'll use GraalVM and SubstrateVM to create minimal statically linked native binaries of our OSGi Features, just the way you like it for a Docker Image.

Are you using Jakarta EE yet? Creating the Jakarta EE project as an open home for Enterprise Java standards is one of the biggest changes in Java’s long history. The most obvious and immediate impact is, of course, that all the API packages changed their names. Look a little closer, however, and the ripples through the rest of the Java ecosystem are still moving. This talk will look at how the changes in Jakarta EE have impacted you not just as a user of the APIs, but also the Open Source projects and other Open Standards that you use as well.

Are you sick of slow JVM/Application startup? Well there is a new OpenJDK project called CRaC which is all about improving JVM/Application startup without using native images. Let me show you how it works and what is in for you.

The standard feature of Records is a convenient way to represent constant classes. Though the use of this has not reached the full potential, this feature is quite a useful one even in standalone cases. This talk will discuss the feature of Records from the concept through implementation with actual code examples. Records also bring along with it the concept of “Compact Constructor”, “Canonical Constructor”, “Components”, dos and don’ts in initializations and so on and so forth.

Type Switches are now part of Java Language albeit with the preview tag. Though similar to traditional constant switch statements in terms of structure but they differ in multiple ways – they now accept type as an expression to switch – essentially they can “switch” on a type. Switching on a type is not as straightforward as switching on constant values – now a particular type can match multiple cases, thanks to type hierarchies. What happens if such a case occur? How does the implementation take care of this? What’s the byte code generated?

Not so long ago, Java lovers were engulfed by a mammoth change— the Lambda Expressions in Java 1.8! However, eclipsed by lambda, minor in its avatar, was an introduction of a new error message - “should not be used as an identifier,...; a prudent observer would know that we are discussing about _, an underscore, which was being removed as a legal identifier, quietly - And it was being promoted to being an integral part of the next wave — Patterns in Java! This talk is all about this major paradigm shift of Pattern Matching that's happening in Java Language now!
