Example 1 with BaseServer

use of org.jgroups.blocks.cs.BaseServer in project JGroups by belaban.

the class ServerUnitTest method testReuseOfConnection.

 * A connects to B and B connects to A at the same time. This test makes sure we only have <em>one</em> connection,
 * not two, e.g. a spurious connection. Tests http://jira.jboss.com/jira/browse/JGRP-549.<p/>
 * Turned concurrent test into a simple sequential test. We're going to replace this code with NIO2 soon anyway...
