      Description

      JGroups does not handle concurrent leaving of nodes correctly. This is a typical use case in cloud environment when scaled down with an autoscaler/manually which we need to handle.

      A simple test can be devised which fails first n (where n>1) nodes from a cluster, reproducer PR https://github.com/belaban/JGroups/pull/397
