JDK 19: revolution is looming!

The JDK-19 landed last month and may look like yet another routine release except it is not: Project Loom has finally delivered first bits! Alhough still in half-incubation / half-preview, it is a really big deal to the future of OpenJDK platform. Interestingly enough, a vast majority of the JDK-19 JEPs are either preview or incubating features. So, what JDK-19 has to offer?

From the security perspective, a few notable changes to mention (but feel free to go over much more detailed overview in the JDK 19 Security Enhancements post by Sean Mullan):

If you are one of the early adopters, please note that JDK-19 introduced a native memory usage regression very late in the release process so that the fix could not be integrated any more (JDK-8292654). The regression has already been addressed in JDK 19.0.1 and later.

With that, hope you are as excited as I am about JDK-19 release, the peaceful revolution is looming! And the JDK-20 early access builds are already there, looking very promising!
