I agree ObjectStreamField is not quite the right place for this method.  
Duplicating this method may be a better option for this case (that I 
typically try to avoid).  I can make this change.

I try to avoid adding a new class just for this one method.  I tried to 
find an existing class for this method but there doesn't seem to have a 
good one.
