Contributions to #OpenJDK don’t have to be huge always. Sometimes it is the small things that have BIG EFFECT. For example if a class was intended to be non-synchronized (hence: fast), implicitly is synchronized by mistake (hence: slow), is finally getting fixed after 30 years. Just few code lines changed, but multiplied by lots of existing #Java applications using that class, makes a BIG EFFECT in sum!
To get this performance optimization, immediately upgrade to JDK 20!
