      The reason is, that PortletResourcesUtil.getPathServletContext will access the ServletContext of the old portlet and in WildFly an undeployed ServletContext is missing the handle of the module and will throw this NullPointerException. On other application servers similar problems will arise.

      The root cause is, that PortletHotDeployListener.doInvokeDeploy calls Portlet.setReady, but PortletHotDeployListener.doInvokeUndeploy forgets to call Portlet.unsetReady.
