When deploying two switchyard applications on the same contextPath SwitchYard seems to run into a race condition which causes a NullPointerException. Here is the log, note the first module deploying on MSC service thread 1-1 deploys and the second appears to be deploying at the same time. If the applications are deployed sequentially it works fine. However, when restarting the server we see intermittent problems starting because of this race condition.
