Re: [Resteasy-users] TJWS - 2.1.0.GA: NPE while using EmbeddedServer from Maven

I do not know the cause of your issue but for what its worth here is 
some code that I have used in my surefire maven plugin without issues:

     protected static void startRestEasy(Class<?> ... classes) throws 
Exception
     {
         server = new TJWSEmbeddedJaxrsServer();
         server.setPort(PORT);
         server.start();
         Registry registry = server.getDeployment().getRegistry();
         ResteasyProviderFactory factory = 
server.getDeployment().getDispatcher().getProviderFactory();

         if (classes != null)
             for (Class<?> clazz : classes)
                 registry.addPerRequestResource(clazz);

         factory.addExceptionMapper(...);
     }

     @BeforeClass
     public static void beforeClass() throws Exception {startRestEasy(...);}
