Vlad Protsenko is a Clojure developer working at Defold. While I initially wanted to learn about the Cljfx project, our conversation evolved into a learning experience: a practical getting-started guide to Clojure, a hands-on demonstration of building JavaFX user interfaces with minimal code, and an inside look at the Defold game engine and its JavaFX-based IDE.

As described before on Java 21+ Not Working on Raspberry Pi Zero 2, a problem appeared to execute Java code on the Raspberry Pi Zero 2 with OpenJDK 21 or higher. Reason: in OpenJDK 21 the Just-In-Time (JIT) compiler has been improved, but this change doesn’t work correctly on the ARM Cortex-A53 processor as used in the Zero 2. It’s another type of processor compared to, for instance, the Raspberry Pi 4 (Cortex-A72) and 5 (Cortex-A76).

These are the links from the Devoxx talk in Antwerp, Belgium, on October 9, 2025: “The Wait is Over: Foreign Function & Memory (FFM) API brings modern Java to the Raspberry Pi”.

2025 is an important year as Java 25 got released, a version which will be supported for many more years. On top of that, the Pi4J library will soon be published as V4.0.0 with a new plugin making use of the FFM API, a new feature added to Java in version 22.

Here is the overview of the JavaFX LinksOfTheMonth of September 2025. You can find the weekly lists on jfx-central.com. Did we miss anything? Is there anything you want to have included in one of the next overviews? Let us know via links@jfx-central.com.

During a live stream coding session, Matti Tahvonen and I updated an existing Vaadin+Spring+Pi4J demo application to use the latest version of the libraries and Java 25. It’s a demo application I created a few years ago to using during presentations at conferences. Of course, everything evolves, so a big update and refactoring was needed.

I created my first IntelliJ IDEA plugin to fix a minor, personal frustration… I have a long list of projects I’m working on and need to switch between them frequently. But it’s hard to locate a specific project in such a long list. But this problem is now solved! I created a small plugin that adds a new option to the “File” menu: “Recent Projects (Organized)”. It shows your recent projects, organized by the first word of their project name. When multiple projects share the same first word, they get grouped in a submenu.

There is only one “Links Of The Week” for August thanks to a nice summer break. So this is actually a “Links Of The Month”… ;-)

Earlier this month, I released V0.0.1 of my new Java library to interact with DMX512 devices using (optionally) the Open Fixture Library (OFL). After some more experimenting, I’m able to announce the next (beta) release V0.0.2 with the following major changes:
