FULL PRODUCT VERSION :
java version "1.6.0_02"
Java(TM) SE Runtime Environment (build 1.6.0_02-b05)
Java HotSpot(TM) Client VM (build 1.6.0_02-b05, mixed mode)
ADDITIONAL OS VERSION INFORMATION :
win2000
A DESCRIPTION OF THE PROBLEM :
Bug 6202684 is still not solved. The problem still exists, when you tab with ctrl-tab from one textarea to another textarea. Sometimes the first character is not shown.
STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Just create several JTextArea components, jump from one textarea to the next with ctrl-tab and type some keys.
Using the Robot-class it should be easy to reproduce the problem (on 1.6.0_05-ea-b04, windows). Only in the first TextArea the first typed key is shown, in every next textarea the first character is lost.
EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The first typed character should be shown always
ACTUAL -
Sometimes the first typed character is not shown.
REPRODUCIBILITY :
This bug can be reproduced occasionally.
