Not sure if you have more changes coming, but there are still a few other places where IAE could be thrown. I would change `getAuthorities()` (in both CertificateRequest.java and CertificateAuthoritiesExtension.java) to catch `IllegalArgumentException` and rethrow it as an `SSLException`, as this will ensure all existing and future calls to this method are handled consistently.

Also, I would change the `toString()` method to also catch IAE but not propagate it, instead print something like "unparseable X500Principal".
