Well, it certainly compiles and runs fine under 1.2.1 and without the 
!java.lang.Object it does not compile ...

It certainly seems desirable to me.  But, I don't see how it could be 
implemented.  Anyway, I'm going to do some decompiling now and have a

Anyway, thanks very much for your replies --- they have been v.useful!
