1. Spring and Java
>> JDK 25 Performance Improvements [inside.java]
JDK 25 shrinks our memory footprint with Compact Object Headers, saving 4 bytes per object to boost cache locality. It also supercharges startup, using new Ahead-of-Time (AOT) profiling. Thanks, I’ll take it 
>> HTTP/3 Support in the JDK [inside.java]
And, looking forward to JDK 26’s new HTTP/3 support – it lets the HttpClient run over QUIC instead of TCP. Very cool.

And an interesting new IntelliJ plugin, focused on getting build insights directly into IntelliJ IDEA. Looks interesting.

2. Technical & Musings
>> Going Further With “One Outcome per Test” [thecodewhisperer.com]
When a single action in a test seems to have two independent outcomes, try modeling them as listeners to a new domain event. This small shift often reveals a cleaner design and helps you spot hidden complications in your workflow much earlier.
