Uneven spacing between attributes in class diagram

[martinburger]

I am using MetaUML to generate some simple class diagrams. For example:

input metauml;
iClass.foreColor := (1, 1, 1);

  beginfig(1);
    Class.A("Cat")
      ("active",
       "color",
       "hungry",
       "name",
       "weight")
      ("printInformation()",
        "runAndMeow()");

    Class_noVisibilityMarkers.A;

    drawObject(A);
  endfig;

end

I noticed that there is some uneven spacing between the attributes in the generated PDF document:

Any idea how to make this spacing uniform?
