should (classObj.getLabel() == null) when MAP.LAYER.CLASS has no LABEL ?

[rich.fromm]

Within each MAP.LAYER.CLASS in my *.map files, some classes have a LABEL, but
many do not.  My guess had been that when parsing the classObj in Java
mapscript, that if there was no LABEL, that classObj.getLabel() would return
a
null labelObj.  This is not the case.  A non-null labelObj is returned
whether
or not there is a LABEL.

Is this intended behavior, or a bug?

There's no way to tell from the mapscript docs, as getLabel() isn't even
listed in "classObj Methods".  (Which I guess is a minor documentation bug
regardless.)

If I look at the classObj.java source, it shows:

--- begin ---
  public labelObj getLabel() {
    long cPtr = mapscriptJNI.get_classObj_label(swigCPtr);
    return (cPtr == 0) ? null : new labelObj(cPtr, false);
  }
--- end ---

I don't totally understand all of the SWIG stuff, but I would guess from
looking at it that it ought to be returning null if not applicable.  But it
doesn't appear to be doing that.
