Mark Proctor commented on JBRULES-3079:
---------------------------------------

Vinod: It's always better to log it with a self contained unit test, as we can't just fix something, without a unit test. And if we have to write the tests ourselves it takes us a lot longer to get round to doing it, as we'll find easier things to do :)
