Suggested patch

Is there a convention for whose badges go where?  Otherwise, one badge 
is likely to overwrite another.

Supplied patch applied.

Note that a more sensible way of doing this is:

DataNode.java:

    public java.awt.Image getBaseIcon() {
        return super.getIcon();
    }

    public final java.awt.Image getIcon (int type) {
        img = getBaseIcon(type);

        try {
            img = obj.getPrimaryFile ().getFileSystem ().getStatus 
().annotateIcon (img, type, obj.files ());
        } catch (FileStateInvalidException e) {
            // no fs, do nothing
        }

        return img;
    }

This gives descendents of DataNode the proper behavior, while 
eliminating the need to copy code from superclass to all subclasses.  
With the current design, what happens if the code in 
DataNode.getIcon() needs to change, when there are so many copies of 
it?

The UI site somewhere has a complete badging proposal that specifies
which kinds of badges are permitted to go into each sextant of the
24x16 icon.

Yes the situation with DataNode and its icon is clumsy at times; your
idea may be workable if it can be done compatibly. Bring it up on
dev@openide.
