IV79921: USING MARSHALLER ON XJC GENERATED CLASSES CAUSES JAVA.LANG.CLASS CASTEXCEPTION: JAVA.LANG.LONG CANNOT BE CAST TO JAVA.LANG.STR

APAR status

• Closed as program error.

Error description

• Error Message: java.lang.ClassCastException: java.lang.Long
  cannot be cast to java.lang.String
  .
  Stack Trace: N/A
  .
  

Local fix

• Any of the following  workarounds can be used to avoid the
  error:
  - Remove the annotation from the generated classes.
  OR
  - Have an external binding file
  <jaxb:bindings
  node="//xs:element<OSB>@type='YourSimpleType'<CSB>">
  <annox:annotate
  target="field">@javax.xml.bind.annotation.XmlSchemaType(name="Yo
  urSimpleType")</annox:annotate> </jaxb:bindings>
  OR
  - Change the name of XMLSchemaType to your simple Type.
  

Problem summary

• In JAXB 2.2.7 a  fix has been introduced  in JAXB to impose
  restrictions on simple type like Enum which generates an extra
  annotation @XmlSchemaType  which declares the type of the Simple
  type.However this was not handling a collection like List
  holding a simpleType  of primitive (other than String).In this
  case XJC is generating the annotation @XmlSchemaType
  (type="anySimpleType")  on the List element.
  During runtime, marshaller is parsing the annotation and trying
  to cast the List element to String and resulting in the
  ClassCastException
  

Problem conclusion

• The JAX has been updated to validate the type before generating
  the annotation. No annotation will be generated for primitive
  types.
  This issue is handled in Oracle JDK through
  https://java.net/jira/browse/JAXB-986
  .
  This APAR will be fixed in the following Java Releases:
     8    SR2 FP10  (8.0.2.10)
