(Apple Bug # 2670912, Bugzilla bug # 108030 (click link to see or vote for the bug))
The applet above is signed using Sun's JDK 1.1 javakey signing system using a certificate that expires in 2055.
The certificate works in Internet Explorer 5.1 on OS 10.1 and Netscape 6.2 for OS 10.1.
The problem is that the browsers reports the wrong century if you examine the certificate. When you get the "Java Security Alert" press "More Info" then "Expiration Date" and you are told it is 1955. This works correctly in Internet Explorer 5.0 for OS 9. This does not work using Windows browsers because those browsers use different signing systems. The certificate fails entirely on Applet Launcher for OS X.
Apple has determined that this is a Sun bug.
Workaround: use certificates expiring sooner.
