"The entire java.applet package has been removed from JDK 26, which will release in March 2026," notes Inside Java. But long-time Slashdot reader AirHog links to this blog post reminding us that "Applets Are Officially Gone, But Java In The Browser Is Better Than Ever." This brings to an official end the era of applets, which began in 1996. However, for years it has been possible to build modern, interactive web pages in Java without needing applets or plugins. TeaVM provides fast, performant, and lightweight tooling to transpile Java to run natively in the browser... TeaVM, at its heart, transpiles Java code into JavaScript (or, these days, WASM). However, in order for Java code to be useful for web apps, much more is required, and TeaVM delivers. It includes a minifier, to shrink the generated code and obfuscate the intent, to complicate reverse-engineering. It has a tree-shaker to eliminate unused methods and classes, keeping your app download compact. It packages your code into a single file for easy distribution and inclusion in your HTML page. It also includes wrappers for all popular browser APIs, so you can invoke them from your Java code easily, with full IDE assistance and auto-correct. The blog post also touts Flavour, an open-source framework "for coding, packaging, and optimizing single-page apps implemented in Java... a full front-end toolkit with templates, routing, components, and more" to "build your modern single-page app using 100% Java."

The end of an era, perhaps.

Applets are officially, completely removed from Java 26, coming in March of 2026. This brings to an official end the era of applets, which began in 1996. However, for years it has been possible to build modern, interactive web pages in Java without needing applets or plugins. TeaVM provides fast, performant, and lightweight tooling to transpile Java to run natively in the browser. And for a full front-end toolkit with templates, routing, components, and more, Flavour lets you build your modern single-page app using 100% Java.

As consumers, we don’t really encounter Java that much anymore unless we play Minecraft, but that doesn’t mean Java no longer has a place in this world. In fact, it still consistently ranks in the top three of most popular programming languages, so any tools to make using Java easier, both for programmers and users, are welcome.

Java 25 has been released.

JDK 25, the reference implementation of Java 25, is now Generally Available. We shipped build 36 as the second Release Candidate of JDK 25 on 15 August, and no P1 bugs have been reported since then. Build 36 is therefore now the GA build, ready for production use.

If you want to dive into the details about this new release, feel free to peruse the long, long list of improvements and changes.

More than three years in the making, with a concerted effort starting last year, my CPU-time profiler landed in Java with OpenJDK 25. It’s an experimental new profiler/method sampler that helps you find performance issues in your code, having distinct advantages over the current sampler. This is what this week’s and next week’s blog posts are all about. This week, I will cover why we need a new profiler and what information it provides; next week, I’ll cover the technical internals that go beyond what’s written in the JEP. I will quote the JEP 509 quite a lot, thanks to Ron Pressler; it reads like a well-written blog post in and of itself.

There’s also a third entry detailing queue sizing, and a fourth entry going into the removal of redundant synchronisation.
