Is the string attribute you're marshalling marked as optional? If the binding doesn't say it's optional JiBX won't check for a null value, it'll just try to marshal out whatever is there (and get the NPE if the string is null).

If it is set optional in the binding I'd appreciate any further information you can attach to the bug, such as the actual binding definition for the Change class, the fragment of the XML causing the problem (if you know what it is), and the Change.java code.

Problem in user code. I'm adding the NPE issue as a FAQ item, with some suggestions about tracking it down.
