ACS Java Error "Invalid RSA Modulus Size"

I just added a new certificate to an ACS server with 4.2 installed. The certificate took fine, but after I enabled https the login page will not load the Java applet. I cannot go into the application locally to disable it, because the automatically login locally check box is unchecked. I am looking for a way to disable ssl for CSAdmin via CLI on windows. After this I will request a new certificate and install it.

The Java console shows the following error in it's log:

javax.net.ssl.SSLProtocolException: java.io.IOException: subject key, Unknown key spec: Invalid RSA modulus size.

This is referenced by multiple classes not just javax.net.ssl.

You may try uninstalling and reinstalling the certificate on ACS

Unfortunately the only way I could find to uninstall the certificate was through the web interface. I ended up using firefox (not supported) on a Mac and was able to get in and disable https.
