CXF ignores @XmlAttribute when serializing exception
----------------------------------------------------
Key: CXF-2779
URL: https://issues.apache.org/jira/browse/CXF-2779
Project: CXF
Issue Type: Bug
Components: JAXB Databinding
Affects Versions: 2.2.7
Reporter: Chris Wilson
Attachments: CxfExceptionFieldPropagationTest.java
JAXBEncoderDecoder#unmarshallException} doesn't normally write to private
fields, so exception data isn't propagated, unless:
* either the {...@link @XmlAccessorType} annotation is present on the class and
used to set the default access method to something other than the default
XmlAccessType#PUBLIC_MEMBER,
* or the {...@link XmlAttribute} annotation is present on the individual
private members that you want to be serialized.
The
[http://www.caucho.com/resin-3.1/doc/jaxb-annotations.x...@xmlattribute|Caucho
documentation] says:
bq. Adding @XmlAttribute to a private field will mark that field as
serializable.
{code}
@XmlRootElement
class Bean {
@XmlAttribute("sample-field")
private String _myField;
}
{code}
Nevertheless:
* JAXBEncoderDecoder#marshallException calls
org.apache.cxf.jaxb.JAXBContextInitializer#isFieldAccepted to see whether the
field should be copied
* that method fails to check for the XmlAttribute annotation on the field
* so its value is never serialized or deserialized
and the attached test case fails unless:
* either a public getter and setter are provided to turn the field into a
property,
* or the access type is changed to something other than PUBLIC_MEMBER.
