Description

• camel-spring-boot-starter 2.22.0
  • camel-spring-boot 2.22.0
    •  jaxb-core 2.3.0.1
    • jaxb-impl 2.3.0.1

In some code we have we use JAXB to unmarschall some XML to a POJO class we have containing a RedeliveryPolicyDefinition  as a property. 
This seems to fail without errors and the property remains null.

When we replace jaxb-core and  jaxb-impl version 2.3.0.1 to 2.2.11 the code seems to work again.

Unmarshalling code:

JAXBContext ctx = JAXBContext.newInstance(ErrorHandler.class);
JAXBElement<ErrorHandler> errorHandler = ctx.createUnmarshaller().unmarshal(beanList.item(i), ErrorHandler.class);

Pojo:

@Getter
@Setter
@XmlRootElement(name = "errorHandler", namespace = "http://camel.apache.org/schema/spring")
@XmlAccessorType(XmlAccessType.FIELD)
public class ErrorHandler {
    @XmlAttribute
    private String id;
    @XmlElement
    private RedeliveryPolicyDefinition redeliveryPolicy;
    @XmlAttribute
    private org.apache.camel.spring.ErrorHandlerType type;

XML:

<errorHandlers>
    <errorHandler xmlns="http://camel.apache.org/schema/spring" id="eh-http" type="DefaultErrorHandler">
         <redeliveryPolicy maximumRedeliveries="4" redeliveryDelay="250" backOffMultiplier="2" useExponentialBackOff="true"/>
     </errorHandler>
</errorHandlers>
