FULL PRODUCT VERSION :
java version "1.4.1_01"
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 :
Win XP

A DESCRIPTION OF THE PROBLEM :
UIDefaults Map interface is broken.

UIManager.getDefaults().size() should return the number of
entries in the map. It probably does. But,
UIManager.getDefaults().entrySet().size() returns 0. My
understanding is that both numbers should be the same.


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Run the provided program. Which calls size() and
entrySet().size() on an instance of UIDefaults obtained from
UIManager.getDefaults()




Because an empty entry set and/or key set is returned it is
impossible to iterate through the properties. Perhaps I am
misunderstanding the implementation?


EXPECTED VERSUS ACTUAL BEHAVIOR :
Expected:
566
something is in there
566
566


Actual:
566
something is in there
0
0


REPRODUCIBILITY :
This bug can be reproduced always.
