Hi All,
  With reference to below mail, I just wanted to let you know that
the same code works without any problem if I have an assignment of the
form
   String testString = b.g;
It fails only when I try to assign field of class A with value of field of
class B. Regular variable assignment just works fine.

Thanks and Regards
Shrinivas Joshi.
