This is a User Experience Issue.

When an empty switchyard.xml is deployed, for example because of this bug:

https://bugzilla.redhat.com/show_bug.cgi?id=1041319 , 

an exception is thrown. The bad thing is that the exception says nothing relevant about the problem. It is just NPE.

Thrown exception:

Caused by: java.lang.Exception: {"JBAS014671: Failed services" => {"jboss.deployment.unit.\"DozerTransformationTest.jar\".INSTALL" => "org.jboss.msc.service.StartException in service jboss.deployment.unit.\"DozerTransformationTest.jar\".INSTALL: JBAS018733: Failed to process phase INSTALL of deployment \"DozerTransformationTest.jar\"
    Caused by: java.lang.NullPointerException"}}
