Not possible to disable new TLS extensions for TLS 1.2 connections

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completely broken by small changes as they can contain outdated and poorly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.
