Java desktop apps looked and felt off, because all the windowing toolkits had to reinvent the [windowing] universe from scratch. Cold boots of apps could be painful, as the JVM didn't optimize for that, and actually deploying the apps was not pleasant (fun times guessing how much RAM the app should take as part of the CLI args). Nowadays I have few issues with JVM apps on the desktop other than non-native UI, but that ship sailed a long time ago. And yes, JetBrains is a great example of how to do this well.
