Rajini Sivaram commented on TUSCANY-2343:
-----------------------------------------

Daniel,

I am not sure I missed something, but this stack trace looks exactly the same 
as the previous one.  

Does org.eclipse.eilf.connectivity.framework.sca.ScaDomainActivator set TCCL 
before calling EmbeddedSCADomain.start? If so, is it possible that this bundle 
is being loaded from the cache (could you try -clean option)? I will try to fix 
this in Tuscany this weekend, but at the moment it would be safest to set TCCL 
in all your bundle activators starting SCADomains.

> Currently the design of the OSGi bundles leads to class loading exceptions. 
> There seem to be several reasons for this behavior:
> * reexporting of all libraries without version numbers
> * imports without version numbers
> Please use distinct bundles for 3rd party libraries. That would lead to 
> easier reusage of your bundles in a larger OSGi project.
> The current status leads to undefined system behaviour due to the OSGi class 
> loading concept.
> Please tell if you see a way, how we could support you by achieving this 
> goal. (If a solution is interesting for you)  We are willing to contribute 
> because its a critical project issue for us.
> The problems occur with the current snapshot release. Sorry, I do not know 
> which version to take.
