Last week, I attended an excellent JUG meetup! The attendance at Poznan JUG was great, and the discussions were engaging. The theater venue was simply superb. I'm glad I had the opportunity to share some thoughts on #VirtualThreads and the @helidon-io.bsky.social .

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. github.com/openjdk/jdk/...
