      "I downloaded the early access version of Java 6, and used all the default instalation settings, except I told it not to set itself as the Java for IE or Firefox because I still wanted to use Java 5 for this.

      Now, whenever I load a Applet in Firefox or IE, a progress bar comes up reading "Updating User Cache". This progress bar, never starts moving. In the console window, I can see the following:

      network: No certificate info for unsigned JAR file: <Address of a jar file on web>

      I get a message like this for every applet I have every downloaded, and it getts into an infinite loop going though these files.

      I tried clearing the cache, and then deleting all the .jar files from the cache when this had no effect.

      I now only get the above message for the applet on the web page I happen to load.

      Also noteworthy, is that the applet will start working if I cancel the progress bar, but not if I cancel it too quickly before it appears. (about 10 seconds)

      What is wrong here, and what can I do to try and fix it?

      Update: I tried reinstalling Java 6 with the default broser options set, and I still have exactly the same problem."

      In a followup, the author notes that he could get the problem to go away by running "javaws -uninstall".

      I have also encountered the same problem, running Mozilla 1.7.12 with Mustang b56. After a couple of minutes I gave up waiting for the dialogue to complete. I also saw the problem the author mentions whereby cancelling the dialogue too quickly breaks the applet launch. I had a few cached JWS apps from a Tiger JDK so updating them to Mustang would not seem like an unreasonable thing if it were unobtrusive.

      The problem is made all the worse by two important things. First, it appears to be triggered by an applet launch, with no obvious connection to Java WebStart. Second, the dialogue is very poorly engineered from a human-factors perspective. It looks like something a bit of spyware might be throwing up. Apart from the title bar, nothing ties it to the Java system, and the one graphical logo in the window looks nothing like other Java logos.
