I have a very simple example of a class with a List member that uses polymorphism. The Java code looks like this:

@XmlRootElement(name = "company")
@XmlAccessorType(XmlAccessType.FIELD)
public class Company {

  @XmlElements({
      @XmlElement(type = DesktopComputer.class, name = "desktop"),
      @XmlElement(type = LaptopComputer.class, name = "laptop")
  })
  private List computers;
  ...
}

JAXB serializes the output correctly (or at least in the way that I want it) like this:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<company>
    <computers>
        <desktop id="computer-1">
            <location>Bangkok</location>
        </desktop>
        <desktop id="computer-2">
            <location>Pattaya</location>
        </desktop>
        <laptop id="computer-3">
            <vendor>Apple</vendor>
        </laptop>
    </computers>
</company>

Jackson JAXB annotations wraps each resulting element in the list in a redundant <computers> tag like this:

<?xml version='1.1' encoding='UTF-8'?><company><computers>
    <computers>
      <desktop id="computer-1">
        <location>Bangkok</location>
      </desktop>
    </computers>
    <computers>
      <desktop id="computer-2">
        <location>Pattaya</location>
      </desktop>
    </computers>
    <computers>
      <laptop id="computer-3">
        <vendor>Apple</vendor>
      </laptop>
    </computers>
  </computers>
</company>

How can I eliminate the extra wrapping Jackson is doing to generate the same shape as JAXB?
