--------------------------------------

patch suggestion:
org.drools.base.ClassObjectType::setTypeValue(),122:
current:
            this.valueType = Evaluator.DATE_TYPE;
        } else if ( clazz.isAssignableFrom( Object[].class ) ) {
            this.valueType = Evaluator.ARRAY_TYPE;

patched:
            this.valueType = Evaluator.DATE_TYPE;
        } else if (clazz.isArray()) {
            this.valueType = Evaluator.ARRAY_TYPE;

> if a fact defines a getter with return value type java.lang.Object, the org.drools.base.ClassObjectType::setTypeValue() seems to set the object type to ARRAY_TYPE, because: java.lang.Object.class.isAssignableFrom(Object[].class) == true
