Subject Re: OSGi NP Complete Was: OSGi - deserialization remote invocation strategy

Nope - not at all. I am only trying to convince you that there is no 
reason to involve ServiceRegistrar or SDM for code downloading.

HOW the class resolution is done - is another story.
I actually tend to think in a similar way to what Niclas said:
Do not use OSGi to load proxy class - create a separate ClassLoader - 
but make sure it delegates to the client bundle ClassLoader for
non-preferred classes.
