Please review the backport of 8184157 to 11u:

Bug: https://bugs.openjdk.java.net/browse/JDK-8184157 , review links are 
included there in "links to" section.

Original change: https://hg.openjdk.java.net/jdk/jdk/rev/67cce1b84a9a

11u webrev: https://cr.openjdk.java.net/~akasko/jdk11u/8184157/webrev.00/

11u exported patch with original attribution: 

Patch applies almost cleanly to 11u, only a trivial change is needed for 
copyright year ("2018" to "2013") in 
WindowsAsynchronousFileChannelImpl.java .

Test is included with the patch. While I was unable to reproduce the 
problem with 1000 iterations, it is reproduced always with 100000 
iterations. Also ran relevant regression and compatibility tests.

PS: regarding 13u, patch applies cleanly to 13u-dev, added 
jdk13u-fix-request label to the issue.
