On the contrary, the example you show below is working fine. listValue
returns a jess.ValueVector object, which Jess uses to represent a
list. ValueVector.toString() prints each object in the list, separated
by spaces. Jess values that contain Java objects print as
<External-Address:Class name>. So taken together,

is doing exactly what it should do. IPLLIST contains two items, each
an instance of edu.stanford.smi.protege.model.DefaultSimpleInstance.
Now, it's not doing what you -want-, and that's another matter. Use
the ValueVector API to loop over the elements of the list, and print
each one in some more acceptable fashion. I don't know anything about
the edu.stanford.smi.protege.model.DefaultSimpleInstance class, or I'd
tell you how to do that; maybe simply printing an instance would work:
System.out.print("Results are ");
ValueVector list = r.fetch("IPLLIST").listValue(null);
for (int i=0; i<list.size(); ++i) {
System.out.print(list.get(i));
System.out.print(" ");
}
System.out.println();
