[rules-users] Is InternalRuleBase safe to use?

[Mark Proctor]

If it safe to use in that it works now, but its an internal api so could 
change at any time - so we don't recommend you using it. The correct 
place to set the ConsequenceExceptionHandler is via the 
RuleBaseConfiguration, which allows you to overide it there.
