Have you installed the unrestricted policy into your Jenkins JVM?

By default it limits the maximum RSA key size to something like 2048 or 4096

Thanks stepenconnolly my searching before posting was not turning up anything useful. That was exactly the issue and works now as expected. I will close this out.
