FULL PRODUCT VERSION :
java version "1.4.0_01"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.0_01-b03)
Java HotSpot(TM) Client VM (build 1.4.0_01-b03, mixed mode)


FULL OPERATING SYSTEM VERSION :
Suse 8.0, Kernel 2.4.18

ADDITIONAL OPERATING SYSTEMS :
Windows XP.



EXTRA RELEVANT SYSTEM CONFIGURATION :
Tested against JDK 1.4.0_01

A DESCRIPTION OF THE PROBLEM :
If I add a Action to a JMenu with jmenu.add(new
AbstractAction() {...}); and I change the properties of the
action object, only the Action.NAME and Action.MNEMONIC_KEY
property is changed correctly. The property
Action.SHORT_DESCRIPTION does not change. Especially this is
annoying on I18N programs which fetch their property values
from a resource bundle.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1.Build a action which bounds to some changing property,
e.g. the change of the "locale" property on some "property
provider"
2.Change the property on the "property provider"
3.Action.NAME does change, Action.SHORT_DESCRIPTION does not

EXPECTED VERSUS ACTUAL BEHAVIOR :
The tooltip should change accordingly.

REPRODUCIBILITY :
This bug can be reproduced always.
