(Application|Session|Request)Map.put(key,value) breaks Map-contract, returning
new value, not old value
-------------------------------------------------------------------------------------------------------
Key: WW-3385
URL: https://issues.apache.org/jira/browse/WW-3385
Project: Struts 2
Issue Type: Improvement
Components: Dispatch Filter
Affects Versions: 2.1.8.1
Reporter: Erling Molde
Priority: Trivial
Noticed that the Map-wrapper classes (org.apache.struts2.dispatcher.RequestMap
etc.) returns the new value from put-method.
request.setAttribute(key.toString(), value);
return get(key);
Should be:
V value = get(key);
request.setAttribute(key.toString(), value);
return value;
in order to be consistent with other Map-implementations.
