📢Important Update 📢

Many have asked for more time to submit to the 2026 #JavaOne call for papers. We've extended the deadline until Nov 13th at 11:59pm PT. Be sure to submit your #Java proposal(s) before time runs out:

➡️ social.ora.cl/6013A7UXF

Only 5 days left. Looking forward to reviewing some security related proposals!

Writing GPU-Ready AI Models in Pure Java with Babylon Project Babylon introduces the experimental Code Reflection technology that lets you define machine learning logic in plain Java code, without needing Python or external model files. It then uses Foreign Function and Memory (FFM) API to connect your code to native runtimes like ONNX Runtime for fast inference, including GPU acceleration. Furthermore, the Heterogeneous Accelerator Toolkit (HAT) provides a developer-facing programming model for writing and composing compute kernels, which can be more broadly applied-allowing Java libraries to seamlessly harness GPU power for high-performance computing tasks.

A big thank you to all of you who attended our @devoxx.com talk on writing #GPU ready #AI models in pure #Java!!!

If you wish to revisit the concepts and run the demos, here are the slides:

Give Babylon a try and share feedback with @lizeraes.bsky.social and I!

I love these anti confusion charts at @lizeraes.bsky.social and @ammbra1508.bsky.social 's talk running AI models on the GPU with pure Java at #Devoxx 🤩

JDK 25 has been branched from the main line and is now in Rampdown Phase One: mail.openjdk.org/pipermail/jd...

YouTube video by Java Java 25 Brings 18 JEPs 😱 Inside Java Newscast #92

#Java 25 is frozen! 🧊 It finalizes 11 features in the language (e.g. simplified main), APIs (e.g. scoped values), and runtime (particularly AOT and JFR) and has 7 more in preview. Walk through the complete list in the latest Inside Java Newscast:

JEP 470: PEM Encodings of Cryptographic Objects (Preview) has been targeted to JDK 25 - openjdk.org/jeps/470

This is a Preview API, so we have time to make changes. Let us know if the API is easy to use and satisfies your use cases.

#openjdk #crypto #security #java

#Java 25 is shaping up to be another BIG release! 🚀 Currently targeted final features:

* simplified main
* flexible constructors
* module imports
* scoped values API
* key derivation function API
* compact object headers

"Towards a JSON API for the JDK"

New proposal on the core-libs-dev list for adding a basic JSON API to #Java. That would be a more than welcome addition, in particular considering the envisioned usage once member patterns will be available. Make it So 🤩!

mail.openjdk.org/pipermail/co...

We integrated #java 's new Stable Values feature just now!

This will allow developers and library developers to benefit from the "secret" @Stable annotation that the internal JDK code has been using for years. This can bring significant performance improvements to your code!

One of the nice things is that all required lower-level concepts that are needed to achieve PQC are baked into the core JDK.
Java's long-term commitment (whatever is in the JDK will be supported for many years by different vendors) make it a perfect choice for writing code that needs PQC.
