--- Comment #3 from Mat Booth mat.booth@redhat.com --- (In reply to Robert de Rooy from comment #2)
Found the issue is already reported upstream.
They have a workaround, which is to start Eclipse from a command line using GTK2 as follows: $ eclipse --launcher.GTK_version 2
But when I do that, all I get is the Eclipse splash screen and it does not continue.
That's right, unfortunately due to man-power we can no longer support the GTK2 back-end.
