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 version bundled in the jbpm 5.3.0 setup zipped file. This issue is also mentioned in https://issues.jboss.org/browse/JBPM-3698 . If it is really a bug , any workaround when using jboss 7.1.1 now?
