I've been trying out Krazo, the JSR-371 RI, which builds upon JAX-RS and RESTEasy.
Their Install Guide for Servlet Containers provides a sample web.xml file:

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xmlns="http://java.sun.com/xml/ns/javaee"
         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_4_0.xsd"
         version="4.0">

  <!-- omitted for brevity -->

</web-app>

When I do this, I notice that my application logs the following message *twice*:

org.eclipse.krazo.bootstrap.Initializer.initialize Initializing Eclipse Krazo...

I wonder if this intentional. If not, adding the following to the root `web-app` fixed it for me:

metadata-complete="true"

I first reported this [with Krazo](https://github.com/eclipse-ee4j/krazo/issues/80) as I thought the `metadata-complete` was the problem. But they think it's something in RESTEasy and suggested to report it here.
