Is usage of Drools libraries in SwitchYard service supported in FSW 6?

Issue

• We have business logic in our SwitchYard application that is making use of Drools (BRMS) libraries for arbitrary business logic, as opposed to something like routing logic.
• This is a SwitchYard bean service that uses the Drools API to make business decisions, not routing or anything like that. It is making arbitrary business decisions.
• We prefer not to use SwitchYard's Rules service for some reasons.
• We have a FSW subscription but no BRMS subscription. Is such an use of the Drools libraries in this manner supported with a FSW subscription alone?
