This sample shows how the evolution of a typical file format might happen. In this example XStream is used as primary serialization framework.
It has been designed to highlight the typical faults developers make. It is not a rant about XStream (or similar tools). Instead it is a rant about choosing the wrong tools for the wrong jobs.
This sample shows which problems might occure and how to solve/avoid them.
The javadocs for the model can be found here. The source code is also available.
