Hi, Spring fans! Last week I was in scintilliating Seoul, Korea, and then tantalizing Tokyo, Japan, and now I'm in marvelous Mumbai, India, at the airport, actually, headed to New Delhi, India. It's been a busy week for me and even busier a week for the community, so let's dive into it!

• Java 23 is here! Happy Java 23 day to those who celebrate! Now to wait for SDKMAN to pick it up...
• In last week's podcast episode, I (finally!) got to sit down with Spring creator Rod Johnson.
• Spring Tools has some cool new upgrades.
• I love this documentary looking at the success of Kotlin.
• Nice tip from Spring community member and JetBrains developer advocate Pasha Finkelshteyn: when you put a cron pattern like * 2 */3 * * 2 inside an @Scheduled annotation in a Spring application, IntelliJ IDEA explains what you just wrote!. Speaking of IntelliJ, the new EAP release is out and has some truly cool AI-centric features…

In this wide-ranging interview, I finally sit down one-on-one and talk to Dr. Rod Johnson, the creator of Spring, entrepreneur, venture capitalist, engineer, father, Kotlin fan, AI researcher, and musician, about this, that, and everything in between, fresh off our recent SpringOne presentation on Spring AI with Spring AI founder Dr. Mark Pollack. This is an extra special, extra-long episode!

Hi, Spring fans! Or, I suppose: 안녕하세요, Spring 팬 여러분! I'm writing this from a café in scintillating Seoul, Korea. It's amazing. I've been talking to developers of all stripes who are using and building upon Spring to do all sorts of cool stuff.

And tomorrow, it's off to jolly Japan. I'll be speaking, among other places, at the Japanese Spring User Group in Tokyo. I'd love to see you there!

We've got a lot to cover so let's dive right into it!

• Spring Framework contributor Sébastien Deleuze has a nice sample application demonstrating Kotlin/WASM, leveraging Kotlin serialization on both JVM and in WASM, and using Spring Boot 3.3 and Kotlin 2.0.
• Speaking of Sébastien, I interviewed him, and we talked about all things Spring, AppCDS, GraalVM, Project Leyden, Kotlin, and more.
• I also interviewed Spring founder Rod Johnson yesterday, and we talked about all things Spring, AI, venture capital, and more.
• There’s an interesting discussion on a ticket in Spring Framework around proxies with CGLIB when @Aspect is used.
• Micrometer 1.13.4 is out!…

Dive deep into the world of Spring Framework and Kotlin, GraalVM, Project Leyden, AppCDS, runtime efficiency, Kotlin, and more, with the one and only Sébastien Deleuze! From runtime efficiency to all things Kotlin, this episode is packed with expert insights and valuable information. Don't miss out on this enlightening conversation with a true Spring guru!

Hi, Spring fans! Welcome to another installment of This Week in Spring! It's September 3rd, and I'm still buzzing from the last week's SpringOne extravaganza! Also: I'm tired. Last week was nuts. I'm super glad it happened, but I'm tired. And also buzzing. You know? Surely you don't. I hope not lol. It's confusing. I feel like I am still "on," like there's work to be done for SpringOne. But I think I also appreciate that it's in the rear view window and it's time to focus on what's ahead: Asia! This Friday, I head to Korea, then Japan, then India, and then (not yet confirmed) China. Pay…

Hi, Spring fans! In this installment I talk to the Tanzu legend Chris Sterling, who works on making Spring an even more valuable part of a platform. (This episode was recorded live at the epic SpringOne 2024 event!)

How can Spring Boot developers improve the runtime efficiency of their applications with minimal constraints in order to enjoy those benefits on most applications? The answer is the CDS support introduced by Spring Boot 3.3 which allows you to start your Spring Boot applications faster and consume less memory. It is based on the foundation introduced by Spring Framework 6.1 that I presented a few months ago.

A key point is that this new CDS support provides a different value proposition compared to the GraalVM native image support: the improvements you get with CDS are less dramatic than with…
