Have JetBrains said anything about possibly addressing these issues? Besides the "ew" factor of using anything labeled "Oracle," Oracle Java has been a right royal pain to install and keep up to date ever since they pulled it out of the various distro repositories. (They provide an RPM for downloading, but not a DEB, which makes life even more fun for Debian/Ubuntu/etc. people like me.)

OpenJDK on the other hand is in the repos, and is supposed to be the official Java reference implementation these days anyway (right?), so it seems like at some point it would be good for JetBrains' products to play nice with it...

I use this PPA: http://www.webupd8.org/2012/01/install-oracle-java-jdk-7-in-... -- which has no Java files but can automatically install Java when it gets a new version. It seems decently up to date (though I would recommend never running Java on the web anyway, unless you have to because you live in Denmark).

OpenJDK is more or less on par since version 7.

There's also some vmoptions tweaking you can do to increase performance some more.
