Hi all,
I've been trying to track this down for ages and I finally have a test
case, before I submit a bug report I want to run it by the list. See
the code below:
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;
}
}
---
@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);
}
}
Running this throws a NPE (see below). The second stack trace is my
real error and looks slightly different. These are both caused by a
non-null bound instance being adapted to a null value.
Any reason I shouldn't file this as a bug?
cheers,
dim

Note that I have a very similar NPE which I believe is caused by the same thing:
