[rules-users] Apply role to whole class hierarchy

[Joerg Henne]

After some debugging I was able to shed some light on what causes the
problem, even if I don't fully understand it. The problem is produced by the
event base class, which is declared with @role(event), i.e. (VSCPEvent)
living in a different package than the ButtonEvent. If I move then into the
same package, everything works just fine.
The two package instances are merged in PackageBuilder.mergePackage(...),
but the RuleBuilder still seems to operate on two separate instances, one
with the declarations and Package.isEvent(...) returning true for the
ButtonEvent and the other without them. Unfortunately, as I know too little
about the workings of the various builders, I can't provide you with a
ready-made idea of how to fix the problem.

See https://issues.jboss.org/browse/JBRULES-3587

Thanks
Joerg
