I just tried to run the unmonitored fail-over example in org.eclipse.cdo.examples.server.FailoverExample (InitialMaster, InitialBackup).
First, I run the InitalMaster main program. I get the following exception
Exception in thread "main" org.eclipse.net4j.util.lifecycle.LifecycleException: Could not activate TCPClientConnector[localhost:2.037]
. That means the InitialMaster-Repo can not connect to the InitialBackup-Repo. This is because the InitialBackup main program is not running yet and has not created an acceptor. It is the same vice versa.
