How to rerun failed tests?

[erik.joelsson at oracle.com]

Hello Richard,

No, there isn't a way to do that AFAIK, but it does seem like a good 
idea. The JTREG_STATUS variable isn't currently meant to be a public API 
from RunTests.gmk, but your patch does demonstrate how this could be 
achieved. I've filed https://bugs.openjdk.java.net/browse/JDK-8262132
