> The doc does not specify in what order the fields declared using append() are applied.
So if for example I use CompareToBuilder to build a comparator for a class Complex (2 doubles),
and I use append(c.real) followed by append(c.imag), does the comparison consider the real
or imaginary part "more important" for the final result of the comparison.
> And similarly, the reflection versions also don't specify the order of the fields they
consider.
> Yes, I can experiment to determine the behavior. Which I am about to do. But I am not
comfortable relying on experimentally-determined, undocumented behavior for correcteness.
Which is why I classified this as Major priority, not Minor or Trivial.
