Does GMF touch the .ecore file? [message #65314]

Whenever I create the .gmfgen file (i.e. the GMF generator model) I get
a warning:
------------------
GenModel seems to be stale, would you like to try to reload it?
Resource platform:/resource/<project>/model/<model>.ecore is
newer (Oct 18, 2006) than genmodel (Oct 18, 2006)
....
------------------

I have deleted and recreated (i.e. "derived" via the dashboard) the
..genmodel a couple of times now and the first time after the recreation
there was no such alert, but next time it re-appeared. I haven't changed
anything in the .ecore recently - at least not that I am aware of...

So why keeps GMF alerting me re. that stale .genmodel file???

Is GMF for some reason touching (i.e. updating the date of) the .ecore
file?

No, GMF itself doesn't touch .ecore file. The reason for this warning is
that reloading .genmodel touches .ecore (regardless of the fact .ecore is
not changed), and it happens that timestamp for .ecore is later than that of
..genmodel.

There's some naive workaround to deal with such EMF behaviour, but
apparently it's not working for you. Could you please file a bug to get rid
of this message?

Done - https://bugs.eclipse.org/bugs/show_bug.cgi?id=161641.

I wasn't sure, whether I should file this against EMF or GMF and against
what component but I have high trust in you folks, that you can figure
that out yourself and redirect it appropriately. :-)
