ExSan: "IntelliJ IDEA Community Edition is the open source version of IntelliJ IDEA":
http://www.jetbrains.com/idea/free_java_ide.htmloutrun: takes a bit of getting used to all with no tooltips on mouse hover by default (although you can turn it on nowadays, I've ended up using the key combination way instead).On a sidenote, I don't like start-up times for any of the IDEs I can think of, including {Visual Studio, IntelliJ IDEA, Eclipse}.Even the less-featured Code::Blocks is too slow for my taste.In contrast, text editors (a notepad+syntax highlighting on Windows, vi(m) on POSIX) are instantaneous in this regard.AFAIR, Visual Studio was _much_ snappier in its pre-.NET years...I think that the start-up times should be _aggressively_ optimized -- IMO that's one of the major productivity-affecting bugs in the IDEs nowadays -- and it looks like the idea of counting on the "CPUs will just keep getting faster" hope being fulfilled and holding forever might have turned out to be a classic example of (premature?) pessimization after all..
