use of org.eclipse.persistence.mappings.CollectionMapping in project eclipselink by eclipse-ee4j.

 * a field that is written by another mapping.  There are two possibilities:
 *
 * 1. The conflicting mapping has already been processed.  In that case, we add MultipleWritableMappings
 * exception to the integrity checker right away
 * 2. There are no conflicting mappings.  In that case, we store the list of fields that this mapping
 * has processed on the descriptor for the target so they can be checked as the descriptor initializes.
