Tomas,
The "Unable to create a proxy object..." message is related to blueprint
and is benign (logged as INFO). When registering a service instance, it
tries to create a proxy for it (for the quiesce functionality which isn't
important) - on failure it uses the original instance (lucky for us). This
happens sometimes - not sure why - it's an issue in the Aries Proxy lib. It
would be nice if it used the JDK proxy APIs for interfaces as that's robust
and only used the ASM stuff when proxying a concrete class as the JDK proxy
API doesn't support that. OSGi services normally advertise an interface
anyway (best practice).
