I dislike dealing with the JVM as much as all the non-java programmers but this is trivial on Mac OS X + Linux and is what allows JetBrains to launch on virtually every platform from day 1.
On OSX the JRE installs on demand and requires very little from the user other than clicking OK and a password. On Linux package managers are there for you. In practice, I'd rather not have Java if I don't need it but it's fairly painless to get setup for this sort of thing.
Sidenote: JetBrains makes a great IDE, I always hear python programmers praising pycharm and java programmers praising intellij.
