RFR: JDK8U Backport of 8154017: Shutdown hooks are racing against shutdown sequence, if System.exit()-calling thread is interrupted

[Muneer Kolarkunnu]

Hi All,
 
Please review this webrev for jdk8u backport.
Webrev: http://cr.openjdk.java.net/~akolarkunnu/8191289/webrev.00/
 
Main Bug: https://bugs.openjdk.java.net/browse/JDK-8154017
JDK10 review thread: http://mail.openjdk.java.net/pipermail/core-libs-dev/2016-June/041952.html
JDK10 changeset: http://hg.openjdk.java.net/jdk9/jdk9/jdk/rev/ceeea7370651
 
Change w.r.t JDK9 changeset: Changed only throws Exception to throws Throwable in test case,  as jdk.testlibrary.ProcessTools.executeProcess() throws Throwable in JDK8.
public static void main(String[] args) throws Throwable {
 
Testing: Tested new regression test and all core-libs regression tests on all platforms - there are no new failures.
 
Regards,
Muneer
