Prasanth Jayachandran commented on ORC-148:
-------------------------------------------
This is purely for debugging purpose. Suppressing exception will hide the
reason why SARG evaluation failed. Although SARG is best effort it will be good
to know why something did not happen.
> Move ORC PPD failure messages from WARN to DEBUG level
