• Create an HTML5 project from central
• In JaxRsActivator, change @ApplicationPath("/rest") to @ApplicationPath("rest")
• Do Run As > Run on Server on the GET rest/members endpoint in the JAX-RW Web Services node
• Assert the WS Tester opens with http://localhost:8080/jboss-as-kitchensink-html5-mobile/rest/members
  FAIL : URL is http://localhost:8080/jboss-as-kitchensink-html5-mobilerest/members

JAX-RS doc says leading slashes are not mandatory for @Path, but I didn't see any mention of ApplicationPath (my guess is the rule should be consistent). At least, the application server doesn't puke on it so it's a valid use case to me.
