OK I looked at your error message again and it's actually from the Eclipse installer, not from Eclipse itself. I am using JRE 1.8, straight download and install from 's default download page. As mentioned, I don't use the Eclipse installer either, just copy the package download to the applications folder.
I noticed my Eclipses were taking up over 3GB so just for fun I deleted them all and did a reinstall. Download new one from / (I chose the 'Eclipse IDE for JavaScript and Web Developers', but also successfully used the Java and Modelling packages) Open DMG, drag over to applications, fired it up. The whole process took around 2.-3 minutes, it's downloading ADT as I write this.
Edit: Another tip is to get SAPGUI working first as that's the more sensitive to the Jva environment. Eclipse just works once that's OK. You can get it from OSS.
Run adt-bundle-mac-x1030/eclipse/eclipse. From within Eclipse File -> Install New Software -> Available software sites -> uncheck everything but.
