title: Can't map property when using MapStruct
body: <p>I am using MapStruct library to map objects but I got this error:</p>
  
  <p>Can't map property "java.util.Date aDate" to "javax.xml.bind.JAXBElement ADATE". Consider to declare/implement a mapping method: "javax.xml.bind.JAXBElement map(java.util.Date value)".</p>
