First, analyze using a JFR execution profile to find out which method is taking more time. If that doesn't yield results, use OTel instrumentation (if running on a JVM, use the Java agent) and analyze it using the response trace ID that is taking a longer time. I am using clickhouse+hyperdx for Otel

Isn't it what these agentic AI tools do (like Claude code, junie etc) ?

It will lift Native Image's default closed-world assumption by allowing dynamic loading and execution of classes at run time.
Stay tuned for updates!

What’s new for JFR in JDK 25 JDK 25, to be released on September 16, is set to include three new Java Enhancement Proposals (JEPs) for JFR and several enhancements to the jdk.jfr API and the jfr command.

AOT Method Profiling JEP status has changed to candidate. openjdk.org/jeps/515

In my latest benchmark with Spring Petclinic, it allows to speedup the warmup compared to the regular JIT (red line versus blue one).

Stabilized peak performance is currently slightly lower, but hopefully will be fixed.

Maybe in the future it's possible to get rid of these daemons altogether with the new AOT caching? openjdk.org/jeps/515

Very nice to streamline how to create an AOT cache for your application.

I've been using the Exposed library for a while, and I find that things can get quite complicated sometimes; figuring out the DSL isn't always easy for complex queries. It seems like ExoQuery makes handling those much easier.

Wow, LINQ for #Kotlin Multiplatform! github.com/ExoQuery/Exo.... This looks really nice, especially coming from the developer of zio-quill (LINQ in Scala) 🤯.

A taste what is already delivered and what is coming to JDKs with Project Leyden. The warmup curve for javac compile tasks clearly improve the further you go into the AOT woods.

We just integrated a performance improvement to Java String that will provide a ~10x performance boost in some applications where Strings are used as keys and where the associated values are constant foldable. This will make JDK 25 faster.

To better support virtual threads, JDK 25 increases the max hold count for ReentrantRWLock from 65K to Integer.MAX_VALUE (2.14 B) for improved scalability #jvm - github.com/openjdk/jdk/...

👍 Is Spring AI compatible with Jlama (github.com/tjake/Jlama)? If so, this would enhance its self-contained, eliminating the need for external tools for inference.

Do you have doc for backend kotlin developers who are never used Dagger or any Andoid DI frameworks? I'm looking for some explanations of its core concepts. Also, is it recommanded for ktor Server side apps?

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!

Probably the most impressive and exciting talk I have seen in years! Congrats to @fniephaus.com and Patrick Ziegler for their #wasmio presentation and work on @graalvm.org starting to compile Java applications to WasmGC. Kudos to @thomaswue.dev too.

Nice. If you want to use a pre-compiled library with an existing JVM, I used it from,

This is really cool... One small request, use java HttpClient instead of unirest in the examples.

The `maxParallelForks` configuration exists for test tasks, but I'm wondering why it's limited to them.
