ExtensionsFilter question

[Claudio Tasso]

Hi guys,
I hope that this question is not originated by drinking too much wine 
last night, but  the current version of 
org.apache.myfaces.component.html.util.ExtensionsFilter imports 
"org.apache.myfaces.util.MyFacesJavascriptRendererUtil".
But it belongs to "myfaces-impl", not to "myfaces-commons", so how can 
tomahawk work without "myfaces-impl"?
