Is your bundle importing the package in question? If not, you should
import it in your bundle and then modify the system bundle to export the
package.
If you don't want to import it (which is a bad idea), you could also add
that package to the framework's boot delegation property.
The first option is the best.

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:

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.
