Folks have mentioned Eclipse as an IDE, but there's also Eclipse as a platform. I have three Eclipse RCP apps I use for visualization daily.

I also manage a lot of equipment that requires java webstart to load a configuration GUI to accomplish tasks that would be darn near impossible at a CLI or any other way.

I logged into Cisco TAC the other day. Requires Java for ticket management tasks.

I use some rf propagation tools for a hobby that are java apps.

I make frequent use of Deskzilla. Java app.

I could go for days. I won't.
