[rules-users] java.lang.ClassCastException: [Lorg.drools.rule.Package; cannot be cast to org.drools.rule.Package

[Geoffrey De Smet]

This is a recently known bug in the old RuleAgent api,
use KnowledgeAgent instead.

Because packages can depend on packages, now a list of packages is 
returned (instead of a single Package) and RuleAgent can't handle that.
