It does look like the same issue.
Got the trunk/framework. mvn clean install gives:

Odd. I'll look into building trunk tomorrow, unless someone beats me to it.

If a bundle undergoes a refresh while ipojo is still initializing
components, a deadlock can happen. The issue is that if ipojo is
attempting to register a service, it will be doing it while synchronizing
on the InstanceCreator instance. It will then try to register a service
which requires the framework's global lock.
Registering a service doesn't require a global, just a bundle lock. I
think this could be related to:
https://issues.apache.org/**jira/browse/FELIX-3761<https://issues.apache.org/jira/browse/FELIX-3761>
This avoid grabbing the bundle lock when registering a service, so maybe
it will help your situation. You could try to build the framework from
trunk and see if it makes a difference.
If you aren't able to build from trunk, let me know and I'll try to
publish a snapshot build since I don't think we have a recent one (we
should do this no matter what).

If a refresh is happening in another thread, the refresh will be holding
the framework's global lock, which will then call IPOJO's extender, which
then attempts to call a method on InstanceCreator, hence leading to the
deadlock.
