I\'m trying to get the new 1.7 JDK working with Eclipse (this is Oracle\'s official release).
I don\'t mean just pointing Eclipse to it so you can use it in projects
By default, your MacOSX comes with JRE 1.6.0 which is not suitable for Eclipse. To resolve issue you also need to install JDK 7 which already includes JRE 1.7.0.
Here is link that you can download.
Just select MacOS X version under Java SE Development Kit 7u79 and install it.

After installation this package, Eclipse will start without any more modification.
