FULL PRODUCT VERSION :
java version "1.4.2"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2-b28)
Java HotSpot(TM) Client VM (build 1.4.2-b28, mixed mode)


FULL OS VERSION :

Microsoft Windows 2000 [Version 5.00.2195]

A DESCRIPTION OF THE PROBLEM :
If a component has focus (in this case a text field) and in response to focusLost, focus os back on it, then the event that caused the lost focus (in this case a button push) is lost. This works correctly in 1.3.1.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
run program and push button. Notice that no printout indicating button push occurred appears.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Should get button push event (and then perhaps regain focus on the edit field). Regardless of order, the button push event should be fired.
ACTUAL -
Button push is not fired, instead it is subverted by the focus event handling.

REPRODUCIBILITY :
This bug can be reproduced always.
