Kotlin, companion object and JAXB
Disclaimer: The class Status below is just for showing a problem I have with "real" elsewhere. :)
Let's say I have the following Kotlin class:
@XmlRootElement(name = "Status")
@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(propOrder = ["id", "status"])
class Status(val id: Int, val status: String)
private constructor() : this(id = -1, status = "")
companion object
private var id: Int? = null
If I try to instansiate JAXB with
JAXBContext.newInstance(Status::class.java)
I get the following exception:
[Exception [EclipseLink-50013] (Eclipse Persistence Services - 2.7.1.v20171221-bd47e8f): org.eclipse.persistence.exceptions.JAXBException
Exception Description: The property or field id$1 on the class nu.westlin.kotlin.jaxb.Status is required to be included in the propOrder element of the XmlType annotation.]

I use org.eclipse.persistence:org.eclipse.persistence.moxy:2.7.1.
If I rename the field id in the compainon object to id2 it works and when I marshal an object I get the expected XML.
How do I get JAXB/Moxy to ignore fields in my compaion object with the same name as in the class?
I have tried @XmlTransient but that didn't do the trick.

If the companion id is private, you could make it a file-level var so it won't become a part of the class in the JVM.
