The idea that Java has been destroyed is pretty wild. I don't see how that belief could survive contact with the real world.
My assumption is the poster wants to imply Oracle destroyed the good will and interest for people to start new Java projects after the licensing changes and subsequent shakedown. Java clearly still runs all over the place and will for a while (although plenty of people trying to keep java but get away from oracle).
To be fair, Oracle acquired Java (via Sun) specifically so they could sue Google for billions. They may not have killed Java but it wasn't altruism.
Pretty common attitude from folks who have never worked in one of the BigTech companies where Java rules (Amazon being a prime example). Since they never encounter Java in the "SF-style Startup" world, they assume that it must be dead. Meanwhile hundreds-of-thousands of Engineers deal with hundreds-of-millions (billions?) of lines of Java every day
