In the UnparseableExtension implementation, the private 'why' variable 
can be used to dump the stack trace later.  But as it is used to get it 
exception message only, I updated to store the exception message only. 
The update does not impact the fix.  It is a kind of DiD fix in case it 
is used in a static field in other places.  We can leave it unchanged if 
you like.
