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 gotNullPointerException (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,AlexOn Tue, Feb 7, 2012 at 4:42 PM, Mauricio Salatino <salaboy@gmail.com> wrote:
