Hi.
I've encountered a problem concerning different behaviours between
equinox and felix concerning jars in lib/endorsed (I'm using Karaf).
I've got a bundle A that depends on classes located in a .jar in
lib/endorsed. With equinox, the bundle A has no problems finding the
classes. With felix, these classes are not found.
Typical error messages I've found are:
09:50:39,041 | ERROR | rint Extender: 1 | BlueprintContainerImpl | ? ? | 10 -

I'd be interested in understanding more in details why behaviours
between felix and equinox are different on this point. Pointers to
documentation would be welcome.
