I'm creating json from JAXB annotated classes. While this works fine for
most classes in the code base, I've been having some trouble with
XmlElementWrapper. I've enabled the feature
USE_WRAPPER_NAME_AS_PROPERTY_NAME, yet I keep getting an error about
multiple fields having the same name.
The following is a minimal class to reproduce the problem:
@XmlAccessorType(XmlAccessType.FIELD)
public class MyClass {
@XmlElement(name="value")
private String currentValue;
@XmlElementWrapper(name="previousValues")
@XmlElement(name="value")
private String[] previousValues;
}
The issue was encountered using version 2.5.4 (and reproduced with 2.8.6).
After some investigation I found the cause to be in
POJOPropertiesCollector._renameWithWrappers(). The method looks like it
expects to do a one-one renaming, so having two fields with the same
XmlElement name causes it fall over before it actually reads the name on
the XmlElementWrapper. To me this is odd because you know you may change
some names, so duplicates shouldn't matter until renaming is complete. The
XmlElement annotation on the array should not affect anything because I've
enabled the USE_WRAPPER_NAME_AS_PROPERTY_NAME feature.
I understand that xml and json have different approaches to this, so my
main question is if this is a bug or intentional?
Thanks in advance.
