Martin Kouba I see you submitted the related Jetty bug and confirmed that it was working. Question, did you also test this on a standalone Jetty or only through the API?

The reason I'm asking is that for me it only works when I start Jetty programmatically. If I deploy the generated WAR to a standalone Jetty (jetty-distribution-9.3.2.v20150730) with a specified jetty-context.xml containing

<!DOCTYPE Configure PUBLIC "-//Jetty//Configure//EN" "http://www.eclipse.org/jetty/configure.dtd">

<Configure class="org.eclipse.jetty.webapp.WebAppContext">

    <Set name="serverClasses">

        <Array type="java.lang.String">

            <Item>-org.eclipse.jetty.servlet.ServletContextHandler$Decorator</Item>

        </Array>

    </Set>

</Configure>

I still get a NoClassDefFoundError exception:

2015-08-28 13:12:23.700:WARN:oejd.DeploymentManager:Scanner-0: Unable to reach node goal: started
java.lang.NoClassDefFoundError: org/eclipse/jetty/servlet/ServletContextHandler$Decorator
[...]

I tried it with version WELD-2.3.0.Beta1.
