RubyMine fails to start on Yosemite

Question

RubyMine won\'t start under Yosemite, no loading screen, no error message.

This seems to be caused by the default JVM that comes with Yosemite

EDIT

Answer 1

You shouldn't edit your plist file since it will prevent Rubymine from autoupdating. This is direct from their support pages:

Modifying Info.plist will break the application digital signature and prevent the patch updates. We do not recommend modifying Info.plist file to run under JDK 1.7 or 1.8.

The correct answer is to install Apple JDK 1.6
