Marshaller.marshall throws NPE if an adapter adapts a non-null bound value to null. · Issue #415 · javaee/jaxb-v2 (original) (raw)

The following source code demonstrates the problem:

@XmlRootElement
@XmlAccessorType(XmlAccessType.FIELD)
public class Bar
{
@xmlelement
@XmlJavaTypeAdapter(TestAdapter.class)
private String v;

public Bar()
{
}

public Bar(String v)

{ this.v = v; }

public static void main(String[] args) throws Exception

{ Marshaller m = JAXBContext.newInstance(Bar.class).createMarshaller(); m.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true); m.marshal(new Bar("foo"), System.out); }

}

import javax.xml.bind.annotation.adapters.XmlAdapter;

public class TestAdapter extends XmlAdapter<String,String>
{
public String unmarshal(String v) throws Exception

{ return null; }

public String marshal(String v) throws Exception
{ return null; }

}

Running Bar will give the following:

I believe that the following is also caused by the same problem:
