The serialVersionUID should be in the Serialized Form generated by
javadoc standard doclet.

The following method is missing from javadoc.ClassDoc.

  /**
   * Returns the serialVersionUID for the class represented by ClassDoc.
   * The serialVersionUID is 0L if the class is not Serializable.
   */
  long serialVersionUID();

This capability was not originally implemented due to the complexity involved
in computing the serialVersionUID. The serialVersionUID is simply the
the special static final member serialVersionUID OR it is computed based on
a complex hash including the signatures of almost all the members of the
class. (Actual computation is in java.io.ObjectStreamClass.computeSerialVersionUID() and it is described
in the Object Serialization Specification.)

Initial attempts to access the static final member serialVersIonUID within
javadoc context were not successful in accessing the value of the static final member serialVersionUID. There exists a chance that the static final members
are not initialized yet in the stage of compilation that javadoc has completed.

This bug report is a record that this feature was not implemented originally.
