Oracle Java breaking GNOME VDI desktop on RHEL Workstation 7.3

I'm managing a RHEV VDI workstation environment and we have a requirement to install Oracle Java. Oracle Java appears to install correctly with no issues but after installing it, the Gnome 3 interface comes up as a black screen and you can't get past this screen.

By default the RHEL workstations are using openjdk java. This one appears to have both 1.8 and 1.7 installed.

Anyone seen this before, and have a solution as to how to get Oracle Java and Gnome 3 to play nicely together?

Thanks

Paul
