[rules-users] Drools error log msg?

You likely have configured a DebugAgendaEventListener, which logs agenda
events (rules activated, fired, etc..)
on the standard error rather than the standard output. If you want a
different behavior, remove the listener
and implement one of your own.
These are not errors anyway.
