SpringComponentProvider is dependent on ServletContext which doesn't exist in non-servlet container case

[jerseyrobot]

SpringComponentProvider is dependent on ServletContext which doesn't exist in non-servlet container case. So it will cause ClassNotFoundException in non-servlet container case where ServletContext.class can not be found.

The related code in SpringComponentProvider.initialize

        ServletContext sc = locator.getService(ServletContext.class);

        if (sc != null) {
            // servlet container
            ctx = WebApplicationContextUtils.getWebApplicationContext(sc);
        } else {
            // non-servlet container
            ctx = createSpringContext();
        }
