From 9c769575bfa2a5c9e7078eb2840bba640dc46077 Mon Sep 17 00:00:00 2001 From: Koichi Sasada Date: Fri, 19 Feb 2021 14:57:59 +0900 Subject: invalidate negative cache any time. negative cache on a class which does not have subclasses was not invalidated, but it should be invalidated because other classes can cache this negative cache.
