Xuelei,
I have a sample socket client for the device TLS issue but its
not very helpful as any socket client created on top of JDK will
do, the last problem was apparent only when talking to a specific
hardware device which refused to negotiate TLS session (I've seen
several odd TLS implementations that were intolerant to Java
changes in various ways over the years and compatibility could
always be assured through config changes, this time around less so).
Some of the hardware TLS stacks can range from small oddities to
being completely broken by small changes as they can contain
outdated and poorly implemented TLS stacks that are very
sensitive so even a small change can break them and thats why its
always important to have levers provided to control almost every
aspect of the handshake.
I have a sample in my gist
(https://gist.github.com/amir-khassaia/04347ca88526f4b958b3326968a905c0),
apologies its in Kotlin. When ran with java 8, 9, 10 there were
no issues. With java 11 this worked on most devices but I've had
a device at a remote location that was not in my control that
I've had to diagnose the handshake failure on using java 11 it
was intolerant to TLS 1.2 client hello from Java 11 but fine with
TLS 1.1 as the new extensions are not present. It would be fine
with TLS 1.2 client hello from Java 10 and earlier as I mentioned.

Hi Amir,
Normally, the extension should have no impact if it cannot be
recognized by the server. It's good to be able to disable
extensions if not needed. I need to evaluate the priority of
it although. Did you have a simple test code that I can
reproduce the issue?
Thanks,
Xuelei

Greetings Xuelei,
To follow up on this, the certificate in the connection is a
red herring and not important. It's actually a very unusual
behaviour by talk.google.com
<http://talk.google.com/> endpoint to encapsulate an error
message inside a certificate.
As per the output I included:

This certificate simply masks the TLS interoperability issue
as an untrusted certificate issue.
The fact is, some of the extensions sent by JSSE are changes
to TLS 1.2 to support TLS 1.3, this however affects some
clients adversely in practice and usually JDK provides
properties to turn new enhancements off and work around such
behaviour, for the extensions I mentioned this is not
provided and hence they are always sent for client sockets
unless TLSv1.2 is not in use.
The impact to us is that upgrading to JDK11 means for some
endpoints or devices that are not 100% compliant to the spec
the security is reduced as we have to now work around to
drop connections to these to TLSv1.1 or TLS1.0 or not to
move to Java 11 at all.
My request is simply to have all of the new extensions
configurable on individual basis so that they can be turned
off if needed for compatibility just like most other
security enhancements that were delivered in the past.
It appears some of the issues can come from
- inclusion of RSASSA-PSS alg in TLS 1.2 handshakes but
these can disabled at least
-signature_algorithms_cert and supported_versions extensions
which seem to be hardcoded for TLS 1.2 (I was not able to
conclusively identify which of these caused my troubles)
https://tools.ietf.org/html/rfc8446#section-1.3 does say
that TLS 1.2 clients are affected but in an optional
manner.Just today I've encountered another Java 11 interop
issue with TLS but this time with a physical device which
can have a long shelf life yet running a simple client
socket handshake abruptly terminates the connection upon
client hello (no server_hello at all), and downgrading the
JRE below 11 works fine. I'm including a trace for that as
well: javax.net.ssl|DEBUG|01|main|2019-01-08 13:40:14.395

I've sent my reply earlier but neither got it posted nor
denied notification so trying again.
