Download 14.1.1 without custom jdk

Hi all,

in the download page I can download only the custom jdk version with JDK 1.8.0_40.
This configuration in my Mac Book Pro 17″ mid 2009, OS 10.10.2 requires the fast GPU that drain the battery very fast and use a lot of CPU.

The 14.1.1 can be used also with JDK 1.6?
If yes, where I can download the 14.1.1 without custom jdk?
If no, how can I fix the battery drain or don’t use the fast GPU?

Moreover, if I want to start Intellij with JDK 1.8 there is a way to tell it to not use the Fast GPU?

Thanks.
Stefano
