Description

The serializable class org.drools.core.reteoo.KieComponentFactory declares a non static logger field (currently unused).

Logger logger = LoggerFactory.getLogger(KieComponentFactory.class);

When serializing the object this causes problems if the used slf4j logger is not serializable. This will also cause problems if the used logger is not available during deserialization.

Desired solution

Either declare the logger field as static or remove it since it is unused.
