FULL OS VERSION :
C:\Documents and Settings\ebelin>ver
Microsoft Windows XP [������������������������������������ 5.1.2600]
--(it's localized, Russian version)

EXTRA RELEVANT SYSTEM CONFIGURATION :
Nothing else seems to be relevant: bug was verified on number of other WIndows XP platforms, including US version.

A DESCRIPTION OF THE PROBLEM :
Animated GIF can be played in various Swing component just as regular image... but not inside the JTable component.

In fact, the code I'm attaching below does exactly this: it plays the image outside JTable in a JLabel component and inside JTable, using three different CellRenderers.  The problem is that none of the renderers play the image.  The only effect I was able to achive is:

if you resize the JFrame, then the next frame of animated GIF is shown.  Just start the application, wait till image is played in the top component and try to resize the frame many times.  You will see changes in second and third columns.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Use the source code supplied (you have to find an animated GIF though---there's no way to attach binaries to this form) and see animated GIF fail to play inside of JTable

2. Try to write your own TableCellRenderer to play animated GIFs.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Animated GIF should play inside JTable just as it is played in a regular Swing component.
ACTUAL -
Animated GIF is not played when rendered inside of the JTable.

ERROR MESSAGES/STACK TRACES THAT OCCUR :
No error messages reported by the system.

REPRODUCIBILITY :
This bug can be reproduced always.
