+Subject: [PATCH] Fix sticky pistons and BlockPistonRetractEvent
+
+There is an explicit check in the handling code for empty pistons that
+prevents sticky pistons from firing the event. However when we look back
+at the history we see that this check was originally added so that ONLY
+sticky pistons would fire the retract event. I'm not sure why.
+https://hub.spigotmc.org/stash/projects/SPIGOT/repos/craftbukkit/commits/1092acbddf07edfa4100bc6824504ac75088e913
+
+Over the course of several updates, the meaning of that field appears to
+have changed from "is NOT sticky" to "is sticky". So now its having the
+opposite effect. Only normal pistons fire the retraction event. And like
+all things in CB, it's just been carried around since.
+
+If we are to believe the history, the correct fix for this issue is to
+flip it so it only fires for sticky pistons, but that puts us in a
+bind. It's already firing for non-sticky pistons, changing it now would
+likely result in breakage. Furthermore, there is little documentation as
+to WHY that was ever intended to be the case.
+
+Instead we opt to remove the check entirely so that the event fires for
+all piston types.
