curious JARSigningException behaviour

I'm experiencing a on my jna.jar file only when I turn off the local storage of temporary internet files in the Java control panel.

I have signed the jna.jar file for local use, but the exception does not occur when I am storing the jars files locally.
Only when I uncheck the "Keep temporary files on my computer" option under Temporary Files Settings in the Java Control Panel.

That doesn't make sense. Can someone tell me what's going on here?

I'm a bit confused about the circumstances under which this exception happens. After all, storing the jar files locally and unchecking that check box aren't alternatives. It is possible to do both of them at the same time, isn't it?

Anyway if you tell the Java environment (a) to store a jar file on the client machine and (b) that it can't store files on the client machine, perhaps that would lead to an exception. Seems logical to me anyway.
I agree. Here's the link:
