> Wanting to hand-roll my own rules, I started out by instantiating a KnowledgeBase and went to add a KnowledgePackage. 
> I was then confronted with:
> {noformat}
> java.lang.ClassCastException: com.example.MyKP cannot be cast to org.drools.definitions.impl.KnowledgePackageImp
> 	at org.drools.impl.KnowledgeBaseImpl.addKnowledgePackages(KnowledgeBaseImpl.java:115)
> {noformat}
> .. while API wrappers are appreciated, if one can't pass in alternate implementations of interfaces, the dependency should be on the required type, rather than allowing a ClassCastException to occur at runtime
