[11u] RFR: 8250521 - Configure initial RTO to use minimal retry for loopback connections on Windows

[Mat Carter]

Bump! 

I've been monitoring the jdk11u backports for the last 2 months and seen a number of items move past these two fixes (enhancements).

I just wanted to check that I've not missed a step in the process as they've not been tagged as "request denied"

Note that David Grieve submitted the requests on my behalf

Cheers

Subject: [11u] RFR: 8250521 - Configure initial RTO to use minimal retry for loopback connections on Windows 
 
I'd like to propose the backport of JDK-8250521 and subsequent JDK-8255264 to 11u.

The patch applied cleanly but had no effect as 11u only used PlainSocketImpl whereas tip uses NIOSokectImpl, so I made comparable changes to PlainSocketImpl.

I kept the original changes to support NIOSocketImpl in case its ever backported.  However, I don't foresee pushing the changes to PlanSocketImpl to tip as its not used by default.

Passes all tier1 tests
