I finally managed to get it working, but it required some changes in the existent stuff...

Thank you! But didn't help.
Actually I see some weird behavior. I decided to try referring drools-core using Require-Bundle from my bundle, so I added
<Bundle-SymbolicName>org.drools.core</Bundle-SymbolicName> to a drools-core package, recompiled it and got 
NullPointerException (still without stacktrace) when I tried to deploy new core bundle to a karaf container.

I was able to deploy it after I removed Bundle-SymbolicName and recompiled again.

Thanks,
Alex
