Oliver Rossmueller resolved MYFACES-655:
----------------------------------------

    Resolution: Won't Fix

It's  valid behaviour for a Map not to implement putAll() and clear() but to 
throw UnsupportedOperationException instead. The MyFaces impl follows the JSF 
RI in this aspect to comply with the spec.

> RequestMap doesn't implement putAll as it should

>         Type: Bug
>     Versions: 1.1.0
>     Reporter: Colin Sampaleanu

>
> The JSF description of for the ExternalContext.getRequestMap() method says:
> """Return a mutable Map representing the request scope attributes for the 
> current application. The returned Map  must implement the entire contract for 
> a modifiable map as described in the JavaDocs for java.util.Map. 
> Modifications made in the Map must cause the corresponding changes in the set 
> of request scope attributes."""
> yet MyFaces returns a RequestMap class which throws 
> UnsupportedOperationException for both the putAll() and the clear() methods.
> This is a major bug which will break apps (like mine) that depend on being 
> able to add params via putAll(), for example.
