It's more common in a server environment. I'd expect to see more Java installs as the popularity of JVM-based language implementations rise, such as JRuby, Clojure, and Scala. I am, for instance, working on putting together a JRuby stack for my company's web applications.
My list is jEdit (used on Linux), SmartCVS/SmartSVN (Linux/Win/OS X still get used sometimes, but much less - moved away to git/bzr), Azureus (on OS X, least used of them all thanks to Transmission and now uTorrent).
Interactive response is not measured with a number crunching benchmark. It's measured by UI latency. Eclipse itself (assuming SWT is considered better than Swing) is still remarkably slow when compared to MonoDevelop.
