27   * OSGi service dynamic collection - allows iterating while the underlying
28   * storage is being shrunk/expanded. This collection is read-only - its content
29   * is being retrieved dynamically from the OSGi platform.
30   * 
31   * <p/> This collection and its iterators are thread-safe. That is, multiple
32   * threads can access the collection. However, since the collection is
33   * read-only, it cannot be modified by the client.
