Marko Friedemann commented on FELIX-3059:
-----------------------------------------
Well, regarding the issues that can arise from reexporting, I followed some of
the discussions and feel there are pros and cons to both sides.
The small testcase I submitted was simply to demonstrate the issue and does in
itself not really need to reexport stuff.
The issues arose in the first place when I tried to get eclipse-based bundles
(they call them plugins) to work and eclipse uses this a lot.
Running these on top of (slightly modified) eclipse base plugins on top of
felix does work so far, BTW, and it is actually only a few rather minor issues
that prevent it out-of-the-box.
Considering to put up some blog or something about it, no time atm, though.
Wrt. to reexporting, the plugins I meant to get working also use it and
rewriting them to use package imports instead does not help in the least with
modularity.
In fact, to get them work prior to the fix (done, as I said), I had to import
packages left, right and center, resulting in a jumbled mess that doesn't make
sense (runtime implementation classes from at-first-glance completely unrelated
bundles all over the place). So, to summarize, there sure are uses cases for
reexporting. :>
Anyway, sorry for the wall of text and thanks again. Now hopefully jbosgi will
pick this change up and start working, better, too.
