Should JDK-8263442 be back ported to jdk11u-dev?

[Vladimir Kempik]

Hello, I thought I would ask first, before attempting backport.
I have found an incorrect usage of http_proxy and authenticator in IntelliJ platform, the issue manifestated itself only after https://bugs.openjdk.java.net/browse/JDK-8263442 <https://bugs.openjdk.java.net/browse/JDK-8263442> .
It seems JDK-8263442 should be backported to jdk11u, but may cause compatibility issues for some.
What do maintainers of jdk11u think ?
Regards, Vladimir
