Java signed applet certificate revoked only on mac OSX10.7 (Lion)

I have a signed applet that works fine on windows, Mac <= 10.6, and linux. However, on OSX lion, the signing certificate is revoked. Here is the security debug info from the java console:

Would appreciate any tips on how to get the signed applet to work on Lion.

UPDATE:

here is the serial number for the cert: 28 A9 29 38 64 0D FC 5D 7D 1D 05 CE 7F 1D 81 E0

I noticed the following, on snow leopard, if I go to advanced settings of java preferences and enable "Check certificates for revocation using CRL" I get the same issue as in lion.

I check lion java preferences and the option was disabled yet the certificate is still revoked

On snow leopard, I disabled the option again and everything works fine

Maybe Java uses the global preference settings in the "Keychain Access" application? This application can be found under Applications > Utilities > Keychain Access.

Default settings indicate:

Online Certificate Status Protocol (OCSP): Best attempt
Certificate Revocation List (CSP): Best attempt
Priority: OCSP

You could verify if the application accepts your certificate if you (temporarily) turn OCSP and CRL off.

In any case, you should probably not be using a revoked certificate... :-)

Have you tried it on a non-lion machine that has never run your applet before? Maybe the other machines that you tested with already trust your applet.
