Incompatible change in the java part of XML project file.

Hi,
I am going to do an incompatible change in the Java Module part of the
XML project file. 
The change involves the declaration of the JavaSourcesRoot's
nb-java-project-rootFolder where the type of the binding is going to be
changed from the FileSet into the URL.
>From the developer point of view the instance file
"nb-java-project-rootFolder" in the Ctx folder must be replaced by

<attr name="BINDING:nb-java-project-rootFolder" urlvalue="The URL which
was in the file set."/>

I am going to fix the modules in the netbeans code base (java,
jarpackager, web).
