Java HotSpot(TM) Client VM (build 1.3.0rc2-Y, mixed mode)

A signed applet jar file that has a jar index will get
a "sun.misc.InvalidJarIndexException: Invalid index!" when being loaded on a
Win 95 or Win 98 machine when using plugin cacheing
(i.e. "cache_option=plugin"). This happens with Internet Explorer (5.0) or
Netscapse 4.7. This is does not happen on Windows NT 4.0 SP5. On Windows NT
everything works fine.

The applet jar file is signed using Netscape's signtool v1.3. A jar index is
then inserted into the jar file using "jar -i applet.jar netscape.jar xml.jar".
The applet will run on all platforms (Win 95, Win 98 and Win NT) as long as
plugin caching isn't used. When plugin caching is enabled by adding the
following parameters to the <OBJECT> tag

<param name="cache_option" value="plugin">
<param name="cache_archive" value="applet.jar, xml.jar, netscape.jar">
<param name="cache_verions" value="0.0.0.1,0.0.0.1,0.0.0.1">

we get the "sun.misc.InvalidJarIndexException: Invalid index!". Here is the
complete stack trace:
