You might very well be right now but IIRC between 2009 and 2012 this was hit-and-miss for me. I cannot remember which applications anymore but I was a Java programmer back then as well.
I've seen keyboard issues in JVM based IDEs before, specifically Webstorm.
I've also seen some keyboard shortcuts not mapped properly in Firefox and Chrome. e.g. in the Chrome console the home and end keys don't work as expected under macOS
I always assumed these were cross-platform library issues but I don't know for sure.
