In bmc-resteasy-client-configurator/pom.xml there is a dependency on resteasy-client, for no good reason. The dependency needs to be on resteasy-core.
There are also some sketches in this file that seem to indicate that what is really desired is an entry in ../../pom.xml's <dependencyManagement> section, so that the Apache httpcomponents stuff is version managed all the way down the dependency tree. What is currently present in this pom.xml file does not accomplish what it seems to want to accomplish.
