The credit node in the transaction-propagation demo starts with port-offset, and the -Pdeploy maven execution fails with following error:

[ERROR] "operation" => "read-attribute",
[ERROR] "address" => [],
[ERROR] "name" => "launch-type"
[ERROR] }': java.net.ConnectException: JBAS012174: Could not connect to http-remoting://127.0.0.1:10999. The connection failed: XNIO000812: Connection closed unexpectedly

Apparently wildfly-maven-plugin has a issue when it connects to non-default port. If I specify protocol option as "remote", then it succeeds, so I guess the default protocol changes when port option is specified.
