FULL PRODUCT VERSION :
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.1_01-b01)
Java HotSpot(TM) Client VM (build 1.4.1_01-b01, mixed mode)

FULL OPERATING SYSTEM VERSION :
Microsoft Windows 2000 [Version 5.00.2195] SP 3

A DESCRIPTION OF THE PROBLEM :
If you Encode a java.util.HashMap containing en entry with
a "Key" and "null" for the value, then this entry will not
be included in the XML output.



STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Create a new java.util.HashMap
2. Add some entries using the "put" method
3. Add one entry like the following put("Key1", null);
4. decode the map using the java.beans.XMLEncoder

EXPECTED VERSUS ACTUAL BEHAVIOR :
Expected result:
<?xml version="1.0" encoding="UTF-8"?>
<java version="1.4.1_01" class="java.beans.XMLDecoder">
 <object class="java.util.HashMap">
  <void method="put">
   <string>Key4</string>
   <string>4</string>
  </void>
  <void method="put">
   <string>Key3</string>
   <null/>
  </void>
  <void method="put">
   <string>Key1</string>
   <string>1</string>
  </void>
  <void method="put">
   <string>Key5</string>
   <string>5</string>
  </void>
  <void method="put">
   <string>Key2</string>
   <string>2</string>
  </void>
  <void method="put">
   <null/>
   <string>6</string>
  </void>
  <void method="put">
   <string>Key7</string>
   <string>7</string>
  </void>
 </object>
</java>




Actual Result:
<?xml version="1.0" encoding="UTF-8"?>
<java version="1.4.1_01" class="java.beans.XMLDecoder">
 <object class="java.util.HashMap">
  <void method="put">
   <string>Key4</string>
   <string>4</string>
  </void>
  <void method="put">
   <string>Key1</string>
   <string>1</string>
  </void>
  <void method="put">
   <string>Key5</string>
   <string>5</string>
  </void>
  <void method="put">
   <string>Key2</string>
   <string>2</string>
  </void>
  <void method="put">
   <null/>
   <string>6</string>
  </void>
  <void method="put">
   <string>Key7</string>
   <string>7</string>
  </void>
 </object>
</java>


REPRODUCIBILITY :
This bug can be reproduced always.
