	* java/util/TreeSet.java (writeObject): Use a for-loop instead of
	Iterator.hasNext().

2001-03-05  Jochen Hoenicke  <jochen@gnu.org>

	* java/util/TreeMap.java (writeObject): Use defaultWriteObject()
	instead of the new JDK1.2 API.  This is simpler and makes
	back-porting the classes to JDK1.1 trivial.
	(readObject): likewise.
