At the moment, if you have debug logging turned on for the `HttpURLConnection`
class, then from [line
746](https://github.com/openjdk/jdk/blob/master/src/java.base/share/classes/sun/net/www/protocol/http/HttpURLConnection.java#L746)
a log message like this is generated:
> sun.net.www.MessageHeader@49c4f2906 pairs: {null: HTTP/1.1 200}{Content-Type:
> application/json}{Transfer-Encoding: chunked}{Date: Thu, 09 Nov 2023 11:50:00
> GMT}{Keep-Alive: timeout=60}{Connection: keep-alive}
The lack of separation after the `Object.toString()` output makes it hard to
realise from the above that it's trying to say "6 pairs".
The change proposed by this PR would make the same log operation output this,
instead:
> sun.net.www.MessageHeader@49c4f290 6 pairs: {null: HTTP/1.1
> 200}{Content-Type: application/json}{Transfer-Encoding: chunked}{Date: Thu,
> 09 Nov 2023 11:50:00 GMT}{Keep-Alive: timeout=60}{Connection: keep-alive}
