Omit wrapper tags in JAXB when the collection is empty

In JAXB, you can use the @XmlElementWrapper attribute to specify tags to wrap a collection of elements. However, these wrapper tags appear even if the collection is empty (they don't appear if the collection is null). Is there any way to have JAXB omit the wrapper tags if the collection is empty? Using adapters on the collection doesn't seem to work, since JAXB interprets this to mean it should apply the adapter to each element in the collection.
