#VirtualThreads changed significantly in JDK 24 & 25.

JEP 491 fixes monitor pinning, but new bottlenecks emerge in connection pools, rate limiters, and ThreadLocal caches that no longer behave as expected.

This #InfoQ article explains what to audit before adopting virtual threads, with guidance backed by a public benchmark.

#Java #JDK25 #JEPs

🎉 Ah, another Java API proposal! Because who needs external libraries when we can have a "simple" JSON parser that's been "incubating" longer than some species of birds incubate their eggs? 🐣 Let's kick back and wait for the next superseding JEP to hatch. 🥚🚀

Last night I wrote a small #Java application, nothing fancy, command line parsing with PicoCLI, http client usage and Jackson JSON processing. Fast enough, but wanted to try out #AOT cache from #JEPs 483, 514 and 515 and it just works. Cuts the execution time in half. Very nice.
