The JVM isn't a language. Kotlin, Scala, Clojure, and Java are languages. I'm quite pleased there are an abundance of options when picking a runtime. Yes, Oracle has not been a good steward, so having numerous open and free alternatives is a positive thing.
Oracle bas been and continue to be a good steward. Who finished the open-sourcing of OpenJDK to the point where it is feature-equivalent to their OracleJDK? Who pays for 98%+ of developers actually working on OpenJDK, on which other companies build their tiny modifications to create a “new” runtime? Who finances GraalVM and other top-notch research?
You can hate oracle all you want for some of their other segments, but they are insanely good at managing the Java ecosystem and we should be thankful for that.
This is a very valid counter-argument and perhaps I've been influenced by Oracle's general reputation, as well as not fully understanding who is responsible for the various open-source builds. I agree that the JVM is a fantastic platform and if it's Oracle putting in most of the work and the funding then I take my statement back.
That's true, but a little pedantic. If you look at it from the lens of "I've picked a language (java), now I need to build and run/deploy things", it's a confusing ecosystem. There's good arguments for why things are the way they are. But there's not really a good argument that it's straightforward and simple.
You are not making a coherent argument. Once you have decided you're building your server app in Java, it is MORE difficult to evaluate and decide Ubuntu, Debian, Red Hat, CentOS, etc. than it is to pick a runtime. Whether it has been like that "from day one" to use your term, is irrelevant. Secondly, having choice is GOOD. Yes it adds a bit of confusion but I'd rather have options than not. If you want some overriding authority to make all the decisions for you, go build on iOS.
Lol, you just can't leave this alone. Choosing a JVM is about 99% less confusing than the last 20 years of .NET Framework/Core/Mono mess and all its sub-projects (ASP.NET, Silverlight, WinFX, etc). At least in Java if you target v.11 you know to install JDK 11 (or higher). Meanwhile if you write C# v8 you need .NET Framework 4.8 to run it. Or maybe .NET Core 3 - which is now called .NET 5. Then over in Python land you've got IronPython, Jython, Pypy, plus the need to keep v2 as "python" on most Linux'es and "python3" for running/building new stuff. Don't forget virtual environments so you can pip install one version of a certain package while keeping it separate from a different installed version of that same package elsewhere. Java is super simple by comparison.
Just simply issue pkg-manager install openjdk and that’s it. Most vendors are just repackages of upstream, and you more than likely don’t need n years of support.
