I also have the same error message ( could not create Vfs.Dir from url. ignoring the exception and continuing: org.reflections.ReflectionsException: could not create Dir using org.jboss.errai.bus.server.service.metadata.VFSUrlType from url vfs:/content/jbpm-gwt-console.war/WEB-INF/classes/) when deploying jbpm 5.3.0 version to the jboss 7.1.1 .
But it works fine when deploying to the jboss 7.0.2 which is the default version bundled in the jbpm 5.3.0 setup zipped file.It is sad that though many users reports that they have this problem , there still no workarounds or solutions that I can found out
