bugs.sun.com or bugreport.java.com is the right place. That routes the 
bugs to the JIRA, just not automatically to the right project as often 
issues need to be filtered or deleted. The bug tracking is JDK-8203937 [1].

The only platform that I'm aware of that will report the reset when 
reading and allow reading beyond the reset is Solaris and this is only 
because of the way that it reports networking errors to applications. I 
think the behavior change you observe is because the reset is reported 
when writing and this is impacting the reading from the java.net.Socket. 
This is really odd behavior that has been there since JDK 1.4, just not 
noticed because it would attempt to read until it got the reset. This is 
all unspecified behavior so this is why the testing with the changes in 
JDK 11 didn't show up anything. I agree we should just eliminate this so 
that it doesn't impact the read.

Would you have cycles to create a small, and standalone test, that 
demonstrates the issue? This could be something we turn into a 
regression test to test behavior.
