From b76b817629bf1504e3109c9872b250513690561d Mon Sep 17 00:00:00 2001 From: Sean Griffin Date: Fri, 11 Mar 2016 10:14:50 -0700 Subject: Use the most highest priority exception handler when cause is set There was some subtle breakage caused by #18774, when we removed `#original_exception` in favor of `#cause`. However, `#cause` is automatically set by Ruby when raising an exception from a rescue block. With this change, we will use whichever handler has the highest priority (whichever call to `rescue_from` came last). In cases where the outer has lower precidence than the cause, but the outer is what should be handled, cause will need to be explicitly unset.
