successfully outside of Felix.
If I run my example code from the command line (RunFooFromOsgi), no
service providers are found.
Is this the behavior you are expecting?
If I run my example code from within Eclipse, I get the following:
I believe Eclipse boot delegates every package, so your bundles may not
be seeing what you expect them to.

I have a very simple service provider that works outside of OSGi.
I tried using it in Felix but it fails with a ClassCastException.
Is this somehow related to the different class loaders in
the different
bundles?
Probably.
Any suggestions on how to get past this?
Not enough information to say.
