---------------------------------------

             Summary: Special request attributes might not be set with multiple wrappers
                 Key: FELIX-6714
                 URL: https://issues.apache.org/jira/browse/FELIX-6714
             Project: Felix
          Issue Type: Bug
          Components: HTTP Service
    Affects Versions: http.jetty-5.1.20, http.jetty12-1.0.10, http.wrappers6-1.1.4, http.wrappers-1.0.4
            Reporter: Carsten Ziegeler
            Assignee: Carsten Ziegeler
             Fix For: http.wrappers6-1.1.6, http.wrappers-1.0.6, http.jetty-5.1.22, http.jetty12-1.0.12


When multiple layers of the http wrappers are used with custom wrappers in between, special request attributes might not be set properly. This includes attributes for error handling, include/forward request dispatching.
For example:
* the original request is a jakarta.servlet request
* this is wrapper in a javax.servlet request
* which is then wrapper by a javax.servlet request wrapper
* which is then wrapped by jakarta.servlet request wrapper
If now a special attribute is set on the latest request object, the implementation of setAttribute causes it to be set first, but then calls removeAttribute - which in turn will wipe out the value
