No edits to Java SE specification docs. I've taken the opportunity to put a space in some "RFCxxxx" references also as it seems to be preferred approach. I've removed a paragraph in src/java.base/share/classes/sun/security/x509/X509CertImpl.java also which seemed obsolete.
I'd like to push this doc edit to JDK 12. http://cr.openjdk.java.net/~coffeys/webrev.8214532/webrev/ -- Regards, Sean.
