I get the ff. error in Java Console occassionally:

My applet tag is as follows:
<applet codebase="../../applets" code="my.package.MyApplet" class="invisible" id="myApplet">
<param value="value0" name="param0"/>
...
<param value="valueN" name="paramN" />
<param value="folder/myApplet__0.0.1177.jar,folder/commons-io-1.3.2__0.0.1177.jar,..." name="cache_archive"/>
<param value="0.0.1177.0,0.0.1177.0,...," name="cache_version"/>
</applet>
It is important I stress the word "occasionally". Sometimes the applet is initialized without a hitch. This also means that, often, when the browser is restarted, the problem goes away.
I am aware of http://stackoverflow.com/questions/698890/applet-fails-to-load-class-from-jar and http://stackoverflow.com/questions/872905/applet-class-loader-cannot-find-a-class-in-the-applets-jar but I think they are not applicable to my case. SomeClass and MyApplet are in the same jar and the page is being accessed locally.
