You can't have both laziness and immutability at the same time in #java ... until Lazy Constant arrives ... JEP 526: Lazy Constants (Second Preview) is now a Candidate for JDK 26! Read all about it here: openjdk.org/jeps/526

My talk "Java Performance Update 2025: From JDK 21 to JDK 25" for @devoxx.com‬ was accepted! I am looking forward to returning to Antwerp and meeting members of the #java community! I will also do another talk: "Finally, final means final - A deep dive into field immutability in Java"

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/...

#java 's new Stable Values API (Preview) was just targeted for JDK 25! Don't miss my talk at #JavaOne about Stable Values: reg.rf.oracle.com/flow/oracle/...

The new StableValues JEP for #java is now one step closer to being finalized: openjdk.org/jeps/8312611 Stable Values will provide the benefits of final fields but with flexible initialization, much like combining the benefits of final and non-final fields.

The JDK 24 train has left the station, and now we are working on JDK 25. I am hoping to see some cool improvements in this one:
