I don't think the change affects the usage of response headers,
but it might be useful to include in the test a call to getHeaderField(0)
to verify that.
Oh - right - but it will/might affect the toString() of the
response headers, if that is used for logging, isn't it?
Wouldn't the status line now be printed with an additional colon
at the end?

Hi Julia,
Could you verify that `HttpURLConnection::getHeaderField(0)` and
`HttpURLConnection::getHeaderFieldKey(0)` return the same thing
before and after the fix, for all implementations of
`HttpURLConnection` in the JDK?
I believe your test is missing that.
More specifically, I'm referring to this:
https://download.java.net/java/early_access/jdk13/docs/api/java.base/java/net/HttpURLConnection.html#getHeaderFieldKey(int)
"Some implementations may treat the 0th header field as special,
i.e. as the status line returned by the HTTP server. In this case,
getHeaderField(0) returns the status line, but getHeaderFieldKey(0)
returns null."
I wonder if the JDK itself was one of those implementations before
the fix. We do not want to change the behaviour of these methods.

Hi,
Please find below a patch for:
8185898: setRequestProperty(key, null) results in HTTP header without
colon in request
https://bugs.openjdk.java.net/browse/JDK-8185898
According to RFC 2616
<https://tools.ietf.org/html/rfc2616#section-4>, message headers of a
HTTP message must adhere to the format:
field-name ":" [ field-value ]
Previously, the request line was handled like a message header and
MessageHeader::print would omit ":" for message headers with value ==
null to account for the request line. However, this can result in a
regular message header missing the colon if its value is null. To fix
this, MessageHeader.requestLine was added, which is used only for the
status line of a request. Any use of MessageHeader.set(0) and
MessageHeader.prepend() in HttpURLConnection was replaced by
MessageHeader::setRequestLine.
