OpenJDK is faster than GraalVM* It's around twice as fast in one particular area. Read more in my latest tiny blog post at mostlynerdless.de/blog/2026/01...

Any #JavaFX people experience removed nodes being stuck around in memory after they've been removed from the scene graph? If I have a node that has a ~500 MB byte array, and then I remove it, I should be able to expect that to be freeable right? Heap dump GC root for reference

I reverse engineered DexProtector, the security solution protecting applications like Revolut and other banking apps. From custom ELF loaders to vtable hooking, here is an insight into how these protections work and their limitations. www.romainthomas.fr/post/26-01-d...

As an old and somewhat inactive Mockito maintainer I'd like to congratulate Tim for these past years keeping the light on the Mockito project. He his now stepping down. Thank you Tim. github.com/mockito/mock...

I spent about two days learning and implementing atmosphere rendering for planetary views from space. The tutorials and other sources I found on it were prettty lacking in implementation details but I got there in the end. Too late now, but does anyone have any recommends? Should I write an article?

another excellent eBay acquisition

I interviewed @mattcoley.bsky.social about #Recaf and his #JavaFX libraries. But unexpectedly, I got a deep-dive course on #Java byte code, obfuscated code, and how JARs can be (ab)used to hide their real code...! www.youtube.com/watch?v=6NIJ... More info: webtechie.be/post/2025-10...

If you're using the JavaFX "Flowless" library for virtualized controls and are observing sluggish performance, do not add stylesheets to the Virtualized Node. Add them to the Scene. I observed an immediate 10x performance boost by doing this.

I love reading these articles and thinking "Yup, that's us on the job. We're part of the industrial inefficiency complex" Artifactory set up but nobody uses it? 👍 CI jobs with zero caching? 👍 + they can recursively spawn other jobs? 👍 + they can trigger from simple "fix typo" commits? 👍

Now Recaf 4X can inline return values of simple static methods (like a xor string decryption call in this case)

"Sideloading" is the rentseeker word for "being able to run software of your choosing on a computing device you purchased". There is no reasonable case for an operating system developer having a say over what programs you run on your hardware. #android #google

Recaf's interactive deobfuscation window now lets you specify how many passes to run. For some obfuscation patterns that can't be one-shot in one linear pass (opaque control flow leading to more opaque control flow repeated N times) increasing the pass count to N+1 reduces it completely.

JavaFX now has a Headless platform. bugs.openjdk.org/browse/JDK-8... is now Resolved! Pfew, that took me 1 year, 5 months and 29 days. Goodnight! #JavaFX #Java

Australia's decision to require age/identity verification, including facial scans, in order to do a Google search is dystopian. We're watching the death of an open, anonymous internet, and the gradual takeover of information online by the state — under the guise of protecting children.

Updates to how some of the transformers work has cleaned up the output on most obfuscated samples I have. Here's a demo on a Minecraft server plugin getting optimized back to almost perfectly legible source.

Honestly, fuck Hotspot sometimes. A method body can just *lie* about how long its data is. Obviously nobody who makes a class parser is going to be keen on this until they see it in the wild. Does the spec say anything about this? Of course not!

The slides from our @reconmtl.bsky.social talk, "Breaking Mixed Boolean-Arithmetic Obfuscation in Real-World Applications" (CC @nicolo.dev ), are now online! Slides: synthesis.to/presentation... Plugin: github.com/mrphrazer/ob...

Getting tired of the "AI can generate code much faster than you" slogan. Most often, the problem is not generating code. The hard part is understanding the code. What is it doing, how and why? And is that what you expect it to do?

Headless JavaFX platform passes almost all tests, with remaining failures being understood. Time to bring this to the next step: mail.openjdk.org/pipermail/op...

Alright, I rewrote my #JavaFX docking framework, BentoFX, from scratch (again) after incorporating it into multiple projects and learning what the pain points were with the existing architecture. Here's what Bento looks like in practice:

In more positive news, I've made a lot of progress on BentoFX. Its still not at a stable release point, but while working on porting Recaf to use it I noticed and cleaned up a lot of bugs and lacking capabilities.

You have no idea how much pain this stupid white rectangle problem has caused me. Still have zero clue what is causing it... 🥲 #JavaFX

One of my favorite t-shirts. But also a broken promise by a large company. I keep believing it's not too late though. Technically, we already have Java running on iOS. But we need more support, technical and marketing. And courage.

Ever try and put #OpenGL stuff into a #JavaFX scene? I have and was kinda disappointed by the built-in offerings, so I made a simple double-buffered canvas. I also recently saw a comment about Shaders in JavaFX and also demonstrated that at the end too 🎨 www.youtube.com/watch?v=zf7g...

I'm working on a Docking Framework for #JavaFX - Its very much a WIP, but if anyone has a use for such a thing and has feature requirements/ideas I'd love to hear them. github.com/Col-E/BentoFX

don't do drugs kids, you might end up working at Microsoft on flawless blazing fast products like Visual Studio

"JavaFX has a perception problem" 💯 People will say "Why not Compose?" before "Why not FX?" even though Compose doesn't have a functional context-menu component for desktop yet. Compose just has a much better PR department even though for desktop its a much lesser offering. FX needs a PR boost.

Our "javac on #WebAssembly" demo (and code!) for #WasmIO25 is up on GitHub in case you want to play with the new Wasm backend for @graalvm.org! 🚀 More details to follow soon! graalvm.github.io/graalvm-demo...

The comments on this are like if a bunch of vegans walked into a sandwhich shop and got mad that ham sandwhiches were the shop's most popular item. System engineers aren't fans of Java. Web UI designers aren't fans of Java. None of this is surprising, none of these spaces are Java's goals.

I've been plagued by this unintuitive white flickering bug for 2+ years and finally had enough. I made a Java agent that double checks if your calls to JavaFX methods are happening on the application thread. If they aren't you can configure it to warn you via a listener. github.com/Col-E/javafx...
