ProtocolVersion.java
--------------------
Later down, you mention DTLS 1.3 quite a bit (e.g. PROTOCOLS_TO_13),
is this going to cause any adverse reactions since there is no DTLS
1.3 implementation yet?
I removed DTLS 1.3 as we don't actually support it right now.
Ok. Too late now, but I suppose you could have left it as a comment.
static final ProtocolVersion[] PROTOCOLS_TO_13 =
new ProtocolVersion[] {
TLS13, TLS12, TLS11, TLS10, SSL30,
/* DTLS13, */ DTLS12, DTLS10
};
95: Why does this comment say 1.3 if this is a _OF_30?
136-146: These "T" names are a little non-intuitive.
PROTOCOLS_TO_TLS11? Should there be a similar for _TO_TLS13? What
about PROTCOLS_TO_DTLS*?
Updated.
Thanks.
229: I probably don't understand the callers of this code well
enough. If DTLS, you return true if it's DLTS10/12/13 or later. But
false if less. Why are you allowing DTLS 1.0 and all later (unknown)
versions? Same question for the TLS arm. Why fail earlier than
SSLv3, and allow above TLSv1.3? Also suggest you move the 243 into
the else arm.
I added a comment for this method. It is used to check if the requested
version number is beyond the minimal supported numbers. For example, if
client request ox0304, because of version negotiation, 0x0303 (TLS 1.2)
should be negotiated. However, if the requested number is 0x0101, the
receiver should reject the connection as the version number is too small
to be supported.
I see what you're doing, but I'm not understanding why we're not
checking the other direction also?
e.g. if (p < SSLv3 && not SSLv2) || (p > TLSv1.3 ) {
Thanks,
Brad
289: You already checked this condition in 285-287 above. And then
304 is no longer needed.
Good catch!
Thanks,

Also reviewed SSLSocketFactoryImpl.java
BaseSSLSocketImpl.java
----------------------
I don't see where requireCloseNotify is actually being used in the
remaining code. If you are removing this functionality, you should
probably be calling that out in your CSR.
SSLSessionContextImpl.java
--------------------------
The only change here was to reorder the import of Vector (obsolete)
and update the copyright? May I ask why? If this was somehow a
netbeans suggestion, there were several other things that could be
updated that seem more important. e.g. 37-39 could be made final.
207: unnecessary unboxing.

Today, I looked over SunJSSE.java, Utilities.java, and
module-info.java. Mostly nits below, some style things.
Utilities.java
--------------
39: hexDigits can be private.
42: Extra level of indent. 4 or 8.
39-41: Nits: When variables are static finals, they are usually
written uppercase.
115: Extra " " and can we get SNI cap'd?
HostName for server name indication
->
HostName for Server Name Indication
150: Minor Nit: You're concating ("+") and then using
StringBuilder.append(), instead of simply append chaining which
might be slightly more efficient.
167-217: The code looks ok, but this might be reworked to take
better advantage of StringBuilder.append() chaining, rather than the
mix of concat and append here now. e.g. what you did with
toHexString(long). I see much of the same code repeated over and
over here. Can be done later.

Hi,
I'd like to invite you to review the TLS 1.3 implementation. I
appreciate it if I could have compatibility and specification
feedback before May 31, 2018, and implementation feedback before
June 7, 2018.
Here is the webrev:
http://cr.openjdk.java.net/~xuelei/8196584/webrev-full.00
The formal TLS 1.3 specification is not finalized yet, although it
had been approved to be a standard. The implementation is based
on the draft version 28:
https://tools.ietf.org/html/draft-ietf-tls-tls13-28
For the overall description of this enhancement, please refer to
JEP 332:
http://openjdk.java.net/jeps/332
For the compatibility and specification update, please refer to
CSR 8202625:
https://bugs.openjdk.java.net/browse/JDK-8202625
Note that we are using the sandbox for the development right now.
For more information, please refer to Bradford's previous email:
