RFR 8241389: URLConnection::getHeaderFields returns result inconsistent with getHeaderField/Key for FileURLConnection, FtpURLConnection

[Michael McMahon]

Hi,

Could I get the following fix reviewed please? It is related
to the issue reviewed earlier, but requires a code change
instead of a spec update.

Bug: https://bugs.openjdk.java.net/browse/JDK-8241389

Thanks,
