Error description

  • For WebSphere Application Server Liberty with the Java
    Authentication SPI for Containers (JASPIC) user feature
    enabled with a
    javax.security.auth.message.module.ServerAuthModule
    implementation that wraps the HTTP request or response
    objects in a javax.servlet.http.HttpServletRequestWrapper or
    in a javax.servlet.http.HttpServletResponseWrapper instance,
    when an application has been configured with a web filter
    mapped to a URL pattern, either dynamically, using the
    @WebFilter annotation, or in the deployment descriptor, the
    web filter does not receive the wrapped request or the
    wrapped response.

    For WebSphere Application Server Liberty with the Java

    with a javax.security.auth.message.module.ServerAuthModule
    implementation that wraps the HTTP request or response objects

    URL pattern, either dynamically, using the @WebFilter
    annotation, or in the deployment descriptor, the web filter does
    not receive the wrapped request or the wrapped response.
    

Problem conclusion

  • The code was modified to correctly pass the wrapped HTTP request
    and response to the application declared web filters that are
    mapped to a URL pattern.
    
    The fix for this APAR is currently targeted for inclusion in fix
    pack 17.0.0.1.  Please refer to the Recommended Updates page for
