FULL PRODUCT VERSION :
java version "1.4.0-rc"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.0-rc-b91)
Java HotSpot(TM) Client VM (build 1.4.0-rc-b91, mixed mode)

FULL OPERATING SYSTEM VERSION : Bug in java code, will
occur in any OS.


ADDITIONAL OPERATING SYSTEMS : Any



EXTRA RELEVANT SYSTEM CONFIGURATION :
None needed.

A DESCRIPTION OF THE PROBLEM :
  Bug is obvious by looking at the source code for
java.util.HashMap.Entry.setValue() (note that line numbers
included below correspond to the HashMap.java file
distributed with J2SDK 1.4.0-rc):

    653 public Object setValue(Object newValue) {
    654 Object oldValue = newValue;
    655 value = newValue;
    656 return oldValue;
    657 }

Whereas the documentation for java.util.Map.Entry.setValue
() states that the previous value should be returned
instead:

Returns:
old value corresponding to the entry.



This bug can be reproduced always.
