OS: Windows XP SP2
Java: JRE1.4.2u19 + JRE6u22
Once JRE6u22 is installed and New Generation Plug-in is enabled on the system which has
JRE1.4.2 installed, jar file used by JRE1.4.2 won't be cached and jar file is always
downloaded from the server.
The customer initially had JRE1.4.2 installed on the system, and jar file caching was
working as expected. It means, once jar files are cached, it won't be downloaded from
the server and applets were invoked using local cache.
But after installing JRE1.6.0u22, jar file has never been cached and it is downloaded
from server every time applet is called.
This causes significant delay of starting up an applet.
