Richard S. Hall commented on FELIX-3378:
----------------------------------------
It's not clear to me why you are loading an Equinox OSGi framework class while
running on the Felix framework, but ignoring that fact for now...
Are you saying you are trying to load a class from a bundle in your class that
was loaded by the application class loader? If so, there is no way that is
going to work, since the application class loader does not have access to
bundle classes.
Perhaps if your code is intended to run on Equinox, then perhaps that is why it
is trying to load an Equinox-specific class, not sure.
You could also try a newer version of Felix, since that would make it easier
for us to debug.
