> Hi,
> When the following drools + camel example is deployed on Apache Karaf :
> https://github.com/droolsjbpm/droolsjbpm-integration/tree/master/drools-osgi/droolsjbpm-osgi-examples/spring-camel-drools-decision-table
>     features:addurl mvn:org.drools/drools-karaf-features/6.0.0-SNAPSHOT/xml/features
>     features:install drools-module
>     features:install drools-decisiontable
>     features:install kie-spring
>     features:install kie-camel
>     features:install drools-camel-example
> Then, the following exception is created :
> {code}

> It seems that we have 2 issues :
> 1) Even if drools-osgi-integration (fragment bundle) is deployed and classes added to the classloader of drools-compiler, the following error is reported :

> 2) During the creation of kcontainer, something happens as the Map of GAVs is equal to zero, reason why we get a NPE
