Session
Java 21 was released in September 2023 and Java 25 is due in September 2025, so we are just in between these two important releases. This is a very good time to look at what was released in the JDK 21, and what is currently been developed, and could be released in 25. Structured Concurrency is almost there, Data Oriented Programming is taking shape, so we now have a good idea of what it will bring for us, developers.
This presentation covers four of the projects currently been developed by the OpenJDK. First, we will take a quick look at Panama, that released the Foreign Function and Memory API and Valhalla and that is still developing value types and non-nullable types, as well as the Vector API. Then, we will spend some time on Loom, that delivered Virtual Threads, and is still developing Structured Concurrency, to understand why you will need this feature once they are made final. And lastly, we will present Amber, how it implements the Data Oriented Programming paradigm to the Java platform, and how you can leverage this programming model to write better applications, organized in a better way and easier to maintain.
