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
