-------------------------------------------------------------
Reproduced this bug in latest version of CXF 2.7.8 and 3.0.0-milestone1(as well
as in fix version for this bug - 2.7.2). Same situation appears in following
case:
{code:title=CxfRecursiveTypeTest.java|borderStyle=solid}
public class CxfRecursiveTypeTest {
@Test
public void testRecursiveType() throws Exception {
Set<Class<?>> classes = new HashSet<Class<?>>();
Collection<Object> typeReferences = new ArrayList<Object>();
JAXBContextInitializer jaxbContextInitializer = new
JAXBContextInitializer(null, classes, typeReferences);
Method addClassMethod =
JAXBContextInitializer.class.getDeclaredMethod("addClass", Class.class);
addClassMethod.setAccessible(true);
addClassMethod.invoke(jaxbContextInitializer, Validation.class);
System.out.println(classes);
}
public static class ObjectGraphProcessorItem<T extends
ObjectGraphProcessorItem<T>> {
protected T parentItem;
protected List<T> childItems = new ArrayList<T>();
public ObjectGraphProcessorItem(Object object) {
super();
}
public List<T> getChildItems() {
return childItems;
}
public void setChildItems(List<T> childItems) {
this.childItems = childItems;
}
public T getParentItem() {
return parentItem;
}
public void setParentItem(T parentItem) {
this.parentItem = parentItem;
}
}
public static class Validation extends ObjectGraphProcessorItem<Validation>
implements Serializable {
public Validation() {
super(null);
}
public Validation(Object object) {
super(object);
}
}
}
{code}

> Project: CXF
> Issue Type: Bug
> Components: JAXB Databinding
> Affects Versions: 2.7.1

>
> Upgrading from 2.7.0. to 2.7.1 uncovers a stackoverflow in
