Current KieServiceImplTest class uses whole Swarm just to read and resolve a configuration YAML file. As a consequence, tests rely on some dependencies like xalan, xalan-serializer and others to be present in the local Maven repository. However, these dependencies (their specific versions corresponding to Swarm/Thorntail version) may not be present on the classpath which makes the test fail with a clean repo.

The fix would be to replace the whole Swarm instantiation just with a simple ConfigViewFactory instantiation.
