Welcome to the Jungle - A Safari Through the JVM Landscape
Jakarta EE 10 - Simplicity for Modern and Lightweight Cloud Applications

We are happy to announce that Gerrit Grunwald and Ivar Grimstad will be our special guests for this month's meeting who will each present their own talk!

Welcome to the Jungle - A Safari Through the JVM Landscape

OpenJDK with it's Java Virtual Machine is great, but there are many flavours. There is Oracle OpenJDK, Eclipse Temurin, IBM Semeru, Amazon Corretto, Azul Zulu, Alibaba Dragonwell, Huawei Bi Sheng, Tencent Kona and many more. Did you ever ask yourself which one is better, faster, free or something similar? Or do you want to know where the differences are in those distributions?

If so, this session might bring some answers to your questions. It will give you an idea about what the JVM is and will cover all the available distributions, not only of OpenJDK but also of GraalVM, and will try to explain the differences and features of the available distributions. It will also try to give you an idea what JVM to use for specific use cases.

Jakarta EE 10 - Simplicity for Modern and Lightweight Cloud Applications

Jakarta EE 10 is packed with new features for simple development of modern, lightweight enterprise Java applications for the Cloud. The new Jakarta EE Core Profile enables developers to develop microservices with Jakarta EE technologies with runtimes smaller than ever. Jakarta EE Core Profile even makes it possible to compile Jakarta EE applications to native images to reduce the footprint even further.

In this session, we will explore the new features of Jakarta EE 10 in an interactive way packed with live code demos. Among the features we will go through are the new reflection-free programming model introduced in CDI 4.0 Lite and the new Java SE Bootstrap API in Jakarta RESTful Web Services 3.1. But there will be more, so make sure you join this session to get it all!

We will even take a peek into the looking glass to see what we can expect from Jakarta EE 11.
