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.
