[xml-dev] module loader dependent on XMLDataObject

I'm porting my modules to 3.5, and I've got a module with a data
loader declared in the manifest:

OpenIDE-Module-Module-Dependencies:  org.netbeans.modules.xml.tools/1
> 0.8, org.netbeans.modules.xml.tree/1 > 0.8,
org.netbeans.modules.xml.core/1 > 0.8

Name: com/nuance/tools/grxml/GrXMLDataLoader.class
OpenIDE-Module-Class: Loader
Install-Before: org.netbeans.modules.xml.core.XMLDataObject

The GrXMLDataLoader looks like:

public class GrXMLDataLoader extends UniFileLoader
{
    public GrXMLDataLoader() {
        this(org.netbeans.modules.xml.core.XMLDataObject.class);
    }
    protected MultiDataObject createMultiObject (FileObject
primaryFile)
        throws DataObjectExistsException
    {
        return new
org.netbeans.modules.xml.core.XMLDataObject(primaryFile, this);
    }
    ...
}

This works fine in 3.4.1, but when I load the module in the dev
builds, I get:

By the way, the whole reason I have a separate DataLoader for my GrXML
data type is to associate the .grxml file extension with the XML mime
type, and to add some GrXML-specific node actions to the DataNode.

Thanks,
