JavaFX 26 SDKs are available, maven artifacts are being published (but it seems to be a busy publishing day ;) )

Working on OpenJDK for Android: in 43 seconds, I run an app on my phone, make a change in OpenJDK (change dlllookup into dll_lookup), rebuild OpenJDK, link it with my app, push to my phone, run again.
OpenJDK development is extremely efficient.

The openjdk-mobile project (https://github.com/openjdk-mobile) provides daily OpenJDK builds for iOS, packaged as XCFrameworks. Recently, there was a failure because I had to update the bootjdk to 25. Apart from that, very smooth!

Whenever I think Apple anti-developer design/concepts can't be worse, there turns out to be a new low:
I honestly keep wondering why so many (often excellent) developers stick to Apple for developing code?

Every now and then, it's ok to be proud of yourself (I hope).
The fact that we at Gluon, for so many years, are delivering high-quality, secure, free and opensource builds of JavaFX, for different OS'es, archs, providing 2 LTS trains, EA and other versions, as SDKs/jmods/maven artifacts,... is actually pretty amazing. See screenshot below from https://gluonhq.com/products/javafx

We have no devrel/marketing/sales, so I'll say it myself: great job, @gluonhq !

Headless JavaFX platform passes almost all tests, with remaining failures being understood.
Time to bring this to the next step: https://mail.openjdk.org/pipermail/openjfx-dev/2025-June/054648.html

I know that I have ambitious goals in JDK space: OpenJDK/Mobile +tooling, synced OpenJFX building with OpenJDK , and a Headless platform for OpenJFX.
Progress on the latter: 88% of the tests pass.

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.
