java.lang.Objectorg.apache.openjpa.lib.util.concurrent.ConcurrentReferenceHashSet<E>
public class ConcurrentReferenceHashSet<E>
A concurrent set whose values may be stored as weak or soft references. If
 the constructor is invoked with refType set to HARD,
 this uses a JDK1.5 ConcurrentHashMap under the covers. Otherwise,
 it uses a ConcurrentReferenceHashMap.
