[EclipseLink] Issues with ElementCollections of embeddables (EclipseLink Issue 296606)


With weaving enabled, updates on an element collection of embeddables can potentially throw a null pointer exception.

For more information, see EclipseLink Issue report.


Two workarounds are available:

  1. Add the annotation @ChangeTracking(DEFFERED) on the embeddable and set the property eclipselink.weaving.internal to false, or

  2. Set the following properties to false in persistence XML: eclipselink.weaving.changetracking and eclipselink.weaving.internal.
