The JVM and associated ecosystem of libraries and build tools is still well-regarded and popular, even if Java-the-language isn't viewed as sexy.

Java has gotten a bit sexier lately but if it's not for you, you can try Kotlin, Scala, or one of the other dozens of languages that can compile against the JVM.

And of course there is an endless and growing number of code bases in the Java language and that won't be changing anytime soon.

HN self-selects for people searching for the latest things.

solid point

agreed

Java isn't cool anymore. If you looked at the HN front-page you'd think almost all new software is being written in Rust, for example

There was never time when Java was cool. It was always language to get the job done, basically.

There does exist a lot of Java code, and this just seems more like an MS attempt to try to entice them to their "cloud" with their own Java stack.

Even if the world stopped writing new Java tomorrow, Microsoft could see years of growth just from people migrating their existing Java code to Azure.

Android isn't going away anytime soon. Its important to remember the HN is a bubble that may not always represent the broader world...

HN is not representative of pretty much anything. It is very biased self selected sample, basically.
