Socket read timeout resulting in fatal tls alert in jdk 11

Thanks Xuelei, can you share with us any tracking bug related to this?

I also would like to highlight that both oracle JDK11 and OpenJDK 11 are
behaving the same way, we confirmed it with multiple runs on both oracle
JDK11 and openjdk11, i.e tls fatal alert raised on ssl socket read timeout
exception, and this wasn't the behavior with jdk8.

Thanks,
Bharath
