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