[12] RFR: two small javadoc fixes

[naoto.sato at oracle.com]

Hi,

Please review the URL fixes to the following issues:

https://bugs.openjdk.java.net/browse/JDK-8212870 : Broken links for 
www.usno.navy.mil
https://bugs.openjdk.java.net/browse/JDK-8212878 : host in ftp: link not 
found

The proposed changesets are located at:

http://cr.openjdk.java.net/~naoto/8212870/webrev.00/
http://cr.openjdk.java.net/~naoto/8212878/webrev.00/

For the former java.util.Date issue (8212870), it is not actually a 
broken link, but the root CA at the website is not validated, thus the 
browsers will complain. There's nothing we can do from the javadoc view 
point to resolve this. Just replaced the URL protocol to "https" from 
"http". The latter one is simply replacing the obsolete ftp URL to the 
correct one.
