org.osgi.service.prefs.Preferences.keys()
Returns all of the keys that have an associated value in this node. (The returned array will be of size zero if this node has no preferences and not {@code null}!) @return an array of the keys that have an associated value in this node. @throws BackingStoreException if this operation cannot be completed dueto a failure in the backing store, or inability to communicate with it. @throws IllegalStateException if this node (or an ancestor) has beenremoved with the {@link #removeNode()} method.
