Custom error page does not work with Weld & Tomcat7

In my web application I'm trying to use custom error page.

However this does not work with Weld. When I navigate to a non-existing page in my app instead of getting custom error page I see exception from Weld:

SEVERE: Servlet.service() for servlet Faces Servlet threw exception

I thought that this is bug in Tomcat:

https://issues.apache.org/bugzilla/show_bug.cgi?id=50789

however it has been fixed in v.7.0.9

Excerpt from my web.xml:

<error-page>
    <exception-type>java.lang.Exception</exception-type>
    <location>/pages/error.xhtml</location>
</error-page>
<error-page>
    <error-code>500</error-code>
    <location>/pages/error.xhtml</location>
</error-page>
<error-page>
    <error-code>404</error-code>
    <location>/pages/pageNotFound.xhtml</location>
</error-page>

I'm using Tomcat 7.0.19, JSF 2.0 and Weld 1.1.2.

Any ideas what happens?

In context of weld only weld-servlet.jar is present in classpath, nothing more
