❓ What happens when your batch job goes from “it works on my laptop” to out-of-memory errors and accidentally DDoS-ing your own dependencies?

Hugo Marques (Netflix) breaks down the evolution of a high-scale #SpringBoot + #gRPC workload: from single-threaded prototypes to #VirtualThreads & semaphores.

Through practical examples and code walk-throughs, he explores the trade-offs of concurrency tools - and why “just making it async” isn’t enough.

Memory management remains the primary factor for application performance in enterprise Java environments. Between 2017 and 2025, the ecosystem shifted from manual tuning to architectural selection. Industry data suggests that 60 percent of Java performance issues and 45 percent of...

Introduction In this post, we dive into a more advanced topic: pointer arithmetic in Java. With the introduction of the Foreign Function & Memory API (Panama), we can interact with native memory. Usually, when we work with off-heap memory, we use MemorySegment instances to ensure safety. However, creating these objects can sometimes add overhead. In…...

Today is the first day in my life I'm running a Maven build in the debugger to examine a build failure. A Maven plugin had thrown an exception with a mostly useless message. Unfortunately, the original exception was wrapped in such a way as to hide the root cause (running with -e was not enough to expose it).

Things I learned on the way:
- IntelliJ IDEA supports running Maven in the debugger.
- IntelliJ does not support loading the sources (or the decompiled code) of the Maven plugins debugged in this way or to set line breakpoints.
- You can set method breakpoints manually by specifying the class and method names, and they actually work in this setup.
- IntelliJ then shows the stack trace and allows you to inspect the stack frame, but does not show the corresponding code. I had to look at the class names and line numbers in the stack trace, open the sources, and navigate there by hand – and follow along by hand while stepping through the program.
- Running the build in the debugger is awfully slow (giving me the time to write this). It took about half an hour to get to the interesting point (vs. 4.5 minutes when not debugging), and I'm still waiting for the exception to occur.

An interesting experience so far – but not one I would want to repeat often. 😅

2025 was a great year for #Spring and #Java

https://spring.io/blog/2025/12/30/this-year-in-spring-december-30th-2025

Yesterday, on my live coding #Java stream, I spent some time (more than I expected) creating some very rough benchmarks for my #EventSourcing example app, JitterTicket.

I had #Junie write a data generator to create 100 concerts, 1,000 customers, each buying 2-4 tix per concert.

JEP 500 prepares the Java ecosystem for final field integrity in JDK 26 by restricting deep reflection mutations - closing a long-standing loophole in the platform.

What's new:
• Enhances safety & performance
• Stricter encapsulation
• Introduces developer warnings when mutations are attempted

With #SpringFramework 7.0.2 out today (https://spring.io/blog/2025/12/11/spring-framework-7-0-2-available-now), and #SpringBoot 4.0.1 out in 1 week, I guess I'll wait a bit to upgrade my projects.

Which is good, cuz I want to get my #Java #EventSourcing projection code complete before I embark on Upgrading All The Projects.

If you're serious about reducing lead time, rethink #PullRequests. They add async delays, inflate WIP & often fail to catch real issues. @javisan81 explains why trust-first teams review differently.
