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.

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:
