I mean, Java applications work ludicrously well. They're not slow, and they really do run on anything. I'm straight up double-clicking .jar files on Mac and Windows without any problems (on linux double click is kinda a myth so I just "java -jar" it). There are good Look&Feel jars for swing. I just wish Swing itself didn't feel like enterprise programming. Java requires me to be so verbose it feels like I'm doing WebDev again.

I'm convinced all of the mud slung on Java is due to enterprise programs and other software not motivated by quality (more of a "you have no choice but to use this to interact with our hardware/service and we CBA to make multi platform so you're stuck with our lazy java. Oh, and we come from the school of abstracting things to hell because creating more red tape impresses upper management.")

IntelliJ is I think the first application that showed me that Java is Good, Actually™ by delivering on those mythical promises of compatibility and speed.
