FULL PRODUCT VERSION :
Java(TM) Plug-in: Version 1.4.2_05
Using JRE version 1.4.2_05 Java HotSpot(TM) Client VM

ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows XP [Version 5.1.2600]

EXTRA RELEVANT SYSTEM CONFIGURATION :
Object tag is using the cache_archive and cache_version tags.
SunONE is the default configuration.

A DESCRIPTION OF THE PROBLEM :
The jar file is not cached when the page is served from SunOne 6.1.
The jar file is requested 42 times for a single applet. (this slows down load time extremely.)

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Try to cache a jar file when served by a SunONE server.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
It should cache the file
ACTUAL -
It never caches the file and

ERROR MESSAGES/STACK TRACES THAT OCCUR :
No error messages.

REPRODUCIBILITY :
This bug can be reproduced always.

CUSTOMER SUBMITTED WORKAROUND :
The only workaround is to disable jar caching.  Once disabled, it only makes 1 request for the jar file, but obviously it doesn't cache it.
