Roughly; I use neither knowledge API nor tables. However I guess you're
not importing org.drools.base.extractors, so your classloader won't let
drools load that class. There was a heap of drools stuff I've never
heard of but had to import before it worked.
I have tried importing all packages this does not change anything.
