[rules-users] Issue using global 'variable' with Drools 5.2 in DRL

[Swindells, Thomas]

If it a java.util.Date then drools supports comparing them out of the box so you can just do subObjcet.dateField >= now.

Just make sure you don't mix up instances of java.util.Date and java.sql.Timestamp (eg if you have jpa code fetching object from the db) as sun in their wisdom made it that you can't compare them with each other!
