windows_2000
Name: gm110360 Date: 07/25/2002
FULL PRODUCT VERSION :
java version "1.4.0"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.0-b92)
Java HotSpot(TM) Client VM (build 1.4.0-b92, mixed mode)
FULL OPERATING SYSTEM VERSION :
Microsoft Windows 2000 [Version 5.00.2195]
EXTRA RELEVANT SYSTEM CONFIGURATION :
Internet Explorer 5.5
A DESCRIPTION OF THE PROBLEM :
Changing display settings (e.g. color depth) while running
an applet with JRE 1.4 (bug did not occur with 1.3.1),
causes the colors of the applet to go weird and the
(obviously back buffered) applet display stretches/shrinkes.
The Java console shows the stack trace shown below.
REGRESSION. Last worked in version 1.3
STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. run applet with JRE 1.4 in IE 5.5
2. change display settings
3. cause applet repaints
EXPECTED VERSUS ACTUAL BEHAVIOR :
The applet is supposed to survive chaning display settings
with no visual defects.
ERROR MESSAGES/STACK TRACES THAT OCCUR :
