Strange. I had tried it with Isabelle2014-RC4 myself, and doing this
again the problem is still there -- using the "latest" Fedora 20
Heisenbug version, according to the update manager.
The difference is probably due to wmname, which I did not manage to
install on Fedora.
If it works for you with that workaround, we can declare this thread
closed, presuming that it is somehow subsumed by the Oracle announcement
of jdk-7u67: "This release addresses a regression introduced in the most
recent security update." The officially documented regression is quite
different, but who knows how many unofficial changes there are.
