Re: Hierarchies not supported in ToStringBuilder.reflectionToString(this)?

Gary,
The ToStringBuilder initial version does not support superclass/subclass
relationships at all.

I recently updated the CVS copy of the code so that the manual
ToStringBuilder technique does support superclasses:
  return new ToStringBuilder().appendSuper(super.toString()).append("b",
b).toString();

I also commented the reflectionToString() to indicate that it does not
support superclasses. If you would like to supply a patch to support
superclasses, then this would be welcomed.
