I have no insight into why this is happening, but it seems to me that
Strouble is asking for trouble. I don't know your motivation in wanting
such a class, but since it appears from your one example that there is
some relation between the D and the S, would it not be possible to store
only the double value and implement a getter for the String value in
terms of the stored double?
The reason I ask you this is because I have such a class that implements
a TelephoneNumber. It stores it as a ten-digit string stripped of all
formatting, and then has a getFormatted() method that returns a
presentable representation. If this is not going to work with Jibx, it
would be good to know this before I get too far into it, and make other
plans.
