I'm not sure if it is container related, however it seems that the CorsFilter is not picked up automatically although the @WebFilter("/*") should do that:

@WebFilter("/*")
public class CorsFilter implements Filter

Instead I had to manually add to web.xml this:

    <filter>
        <filter-name>edu.harvard.iq.dataverse.filter.CorsFilter</filter-name>
        <filter-class>edu.harvard.iq.dataverse.filter.CorsFilter</filter-class>
    </filter>
    <filter-mapping>
        <filter-name>edu.harvard.iq.dataverse.filter.CorsFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

I also checked in the debugger and without the explicit web.xml doFilter() is not get called.
