Eclipse is used quite heavily in Java shops.
emacs and vim are excellent when you are coding in them for hours a day. You eventually rely on muscle memory. Without practice, a lot of that goes away, ime. I used to use vim and tmux for everything, but as I coded less, I found myself using Sublime more and more. (I'm also on a Mac, where key bindings are, generally, shared across apps, which helps with the muscle memory.)
I was recently working in a, predominantly, Java shop. Most folk were using Eclipse. I used Sublime without any problems. There are a lot of advantages to using Eclipse with Java, especially with large projects or when doing major refactoring.
If you just want get on with Clojure, then I'd use something like Sublime or VS Code. But go ahead with Eclipse if you fancy it. It's always had a reputation for being a bit of a resource hungry app, although perhaps that's changed.
If your JVM is out of date, then it's probably worth bringing it up to date.
