Don't drop UNICAST3 message when the window is not created ----------------------------------------------------------- Key: JGRP-1931 URL: https://issues.jboss.org/browse/JGRP-1931 Project: JGroups Issue Type: Bug Affects Versions: 3.6.3 Reporter: Radim Vansa Assignee: Bela Ban Fix For: 3.6.4 When an application sends first two (or more) messages in parallel and the the second one is marked as DONT_BUNDLE, usually this one arrives as the first one and is dropped (see https://github.com/belaban/JGroups/blob/master/src/org/jgroups/protocols/...). After first message arrives, the connection is properly set up, but we need to wait until retransmission for the message (and other non-OOB) messages to be delivered. In practice this behaviour should be acceptable, but it causes failures in some time-sensitive tests (particularly in Hibernate ORM 2nd level cache).
