I created a bug for equinox weaving:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=356284

Regarding the equinox regions bundle: I did not know it yet and I
implemented my own set of framework hooks. I had a look at equinox regions
now and I will definitely try it out, it sounds promising. Thanks for the
hint.

Cheers, Tobias.
