From 01a357b4e27480844686eb83ef81809a28056e41 Mon Sep 17 00:00:00 2001 From: Jim Hahn Date: Fri, 26 Oct 2018 10:10:28 -0400 Subject: Fix random failures in ManualClientEndTest Don't know if this is the cause of the intermittent failures, but it could be, and it is certainly a bug: the classes manipulate data, that isn't marked volatile, from more than one thread at a time. Updated licenses.
