The first sentence of the javadoc for Bundle.loadClass says:

Doesn't this already imply that one should expect similar behavior to
ClassLoader.loadClass? :-)
Hmmm. Good question. Of course, we probably shouldn't strive to create a
spec that needs to be interpreted by implication. :-P

I would be fine with the statement that Bundle.loadClass behaves as
much like ClassLoader.loadClass as possible. Thanks at any rate, at
least it is clear now that the spec allows the way
we implement it in Felix.
