I had edited java.swg in order to propose this as a patch so that SWIG
will have toString() methods by default.  

I hadn't considered using a locally-modified javabody typemap, since
it would be fragile in the face of swig changes.

That's a much better idea, thanks!  If swig won't produce the
toString() methods out of the box, here's how to do it,
for the record:

%typemap(javacode) SWIGTYPE, SWIGTYPE *, SWIGTYPE &, SWIGTYPE [], SWIGTYPE (CLASS::*)
%{
    public String toString() {
        return "$javaclassname<0x" + Long.toHexString( swigCPtr ) + ">";
    }
%}
