I understand and agree that in corporate enterprise you usually do not control which software is installed in your workstation.

I should note that this JDK 8 migration is for EAP releases (ie early alpha/beta versions of the next major release) and that all installers (windows, osx and linux) offered by Jetbrains come with its own JDK bundled in the installer. So if you happen to work in one of those corporate environments, if you manage to get permission to run this IDEA version, you also get the required JRE to execute the ide included.
