Error-page exceptions

[cesguerra]

Hi

We have some error pages in our application that were working well:

<error-page>
    <error-code>404</error-code>
    <location>/WEB-INF/jsp/error-pages/notfound.jsp</location>
</error-page>
<error-page>
    <error-code>500</error-code>
    <location>/WEB-INF/jsp/error-pages/internalserver.jsp</location>
</error-page>

Our CompressingFilter configuration:

<filter>
    <filter-name>compressingFilter</filter-name>
    <filter-class>com.github.ziplet.filter.compression.CompressingFilter</filter-class>
    <init-param>
        <param-name>includeContentTypes</param-name>
        <param-value>application/javascript,application/json,application/xml,text/css,text/html,text/javascript,text/plain,text/xml</param-value>
    </init-param>
</filter>    
<filter-mapping>
    <filter-name>compressingFilter</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

I think the problem is that CompressingFilter write/close the output stream even with http error codes.

Here I forced an http 404:

I'm using the old Jboss 4.2.3 (http://jbossas.jboss.org/downloads) for compatibility reasons.
