Hi,
It's not about classes (which are correctly loaded by the framework and
fully available when i get in there), but about custom
resources/capabilities that I register in the listener. So yes, it fails,
as the listener cannot load the resources it depends on, which should have
been registered earlier by the same listener. As a workaround I could keep
track of the bundles inside the listener when they have unresolved
dependencies, and register them only when the listener has been called on
all dependencies - but that's quite ugly and risk-prone. I would have
preferred to rely on the fact that events are sent in order - that would be
much more clean and simple.
Given that the spec doesn't mandate reverse-dependency delivery of
RESOLVED events, I think you have no choice but to not depend on it if
you want to run on any given framework implementation.
Having said that, I think it would be possible to modify the Felix
framework implement to approximate this ordering by doing something like
taking the wireMap at the end of markResolvedRevisions and rather than
fire the events in order, it could either create a new listed sorted by
dependencies or somehow recursively traverse it following dependencies.
Feel free to open an RFE (and potentially provided a patch), but again,
even if implemented your bundles could fail on other frameworks.

So, are you saying that when you get a resolved event for some arbitrary
bundle, you are running into issues because some of its dependencies are
not yet treated as if they are resolved? What is the symptom you see?
Well, I just did receive the resolved event for the dependencies (Y,Z)
after receiving the event for the bundle having the dependencies (X),
instead of the opposite. Of course, it's not always the case, it happens
for some bundles only, as the order is random. But yes, all of them are
marked as resolved when I get the first event, and all events will
eventually be sent.
What I'm trying to get at is, why is this problematic for you if you get
them out of order? Are you try to load a class and it fails, for
example. Or does it just make you uncomfortable?

Yes, that's the reverse order, not that this terminology is super
important.
Ok, whatever, just to be sure we were talking of the same order.
