[ovirt-devel] Requiring Java 8 during runtime

[Allon Mureinik]

I think it's a really bad practice to have different modules in the same
project with different language versions.

For GWT it seems to be required, but for the rest of the backend, I think
we should have one patch that moves the entire project in one go.
We can have the various maintainers ack it to show their consent.
