In addition to the features highlighted above, this release also includes a substantial number of bug fixes and enhancements:

Other important changes and updates include:

  • Behavior of @XmlID and @XmlValue annotations has been updated to be JAXB 2.2 RI compatible. Fields annotated with @XmlID must be of type String, classes which contain field with @XmlValue annotation must not extend other type than java.lang.Object. To provide backward compatibility with EclipseLink 2.5.0, annotations @XmlIDExtension and @XmlValueExtension were introduced.
  • Annotations @XmlElementNillable and @XmlNullPolicy are supported in both ElementType.TYPE and ElementType.PACKAGE targets, to enable configuration of @XmlElement nillable parameter and runtime null policy at package level.
