Hi all,
Please review the fix for JDK8u Backport of https://bugs.openjdk.java.net/browse/JDK-8186171 Webrev: http://cr.openjdk.java.net/~rpatil/8186171/webrev.00/ Summary(also added to backport bug description): The back port for test files is not clean back port as all tests files are extending JSR166TestCase.java which was added to JDK 9 as part of HYPERLINK "https://bugs.openjdk.java.net/browse/JDK-8146467"JDK-8146467: Integrate JSR 166 jck tests into JDK repo. This is not present in JDK8 version. Therefore, I have extracted test are relevant to the fix done JDK-8186171 and created a new test file Bug8186171Test.java that contains below two test methods: . testBug8186171NonDeterministic : This method is copy of "testBug8186171" present in "MapTest.java" of original changeset http://hg.openjdk.java.net/jdk10/master/rev/3f5f9bc0bdc2. As it is based on randomization and runs 1000 times, the method name is suffixed with "NonDeterministic". . testBug8186171Deterministic : This is a new method that runs single time as it produces the exact scenario mentioned in JDK-8186171. Therefore, it is not needed to run multiple times to produce the scenario mentioned in bug. Hence the method name is suffixed with "Deterministic" Regards, Deepak
