FULL PRODUCT VERSION :
java version "1.4.0"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.0-b92)
Java HotSpot(TM) Client VM (build 1.4.0-b92, mixed mode)

FULL OPERATING SYSTEM VERSION :
Win2k SP2

A DESCRIPTION OF THE PROBLEM :
XMLEncoder always encodes HashSets and TreeSets as empty
even if they are not empty.

ArrayLists and Vectors are encoded correctly.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. create new HashSet
2. add some elements
3. let the XMLEncoder encode

EXPECTED VERSUS ACTUAL BEHAVIOR :
I expectected:
Sets as well as Lists should be encoded including their
contents.

Reality:
XMLEncoder refuses to write Set contents, though it does
write List contents

This bug can be reproduced always.

  public static void main(String[] args) throws Exception {

    List aList = new ArrayList();
    aList.add("foo");

    Set aSet = new HashSet();
    aSet.add("bar");

    XMLEncoder anEncoder = new XMLEncoder(System.out);
    anEncoder.writeObject(aSet);
    anEncoder.writeObject(aList);
    anEncoder.close();
  }
