Then it is strange that those bugs from sqe was not reported on jdk8. I have run the test from the description of this bug and tests which were reported by Yury on my Ubuntu+gnome3 and all of them passed.
Can you please try to install the latest updates on OEL7(on my system Gnome 3.18 is installed).
