I also patched it for 1.1. Could the people using OSGi/ Oscar try
their stuff against HEAD and see if there is a need for the Wicket
OSGiPath at all?
Also, I'm not totally sure about packaged resource (find it attached).
I keep a reference to the class of the package (as package isn't
serializable), but I am not sure what happens if that class is
deserialized in another environment... will it be loaded by the class
loader we need, or could that be a wrong one?

This approach seems to work. At least my problem has gone, after
Eelco's patch. If anyone needs this functionality in 1.0, I will be
releasing a 1.0.2 later this week. This bug/feature will be in there,
as well as some other backported bugfixes.
