I think it is caused by recent code merge from (?):

http://hg.openjdk.java.net/jdk/jdk10/rev/2e867226b914

Revert this patch, build pass. However, I cannot access JDK-8174962.
Comments
Changed affected 9 version to be the specific 9.0.4 release, since 9.0.1 should be fine as it doesn't have JDK-8174962.

Hi [~adinn], Thank you for the work. Your webrev can be applied to jdk10 repo cleanly, except for some warnings about tabs found instead of spaces. I have launched a JTreg test for your patch. One new failure found with fastdebug build: test/hotspot/jtreg/gtest/GTestWrapper.java. Error log attached as hs_err_pid24224.log. Could you please take a look? The following commands can reproduce the failure: $ make images && make test-image-hotspot-jtreg-native && make test-image-hotspot-gtest $ jtreg -othervm -a -va -testjdk:./images/jdk -server -nativepath:./images/test/hotspot/jtreg/native ~/Work/jdk/master/jdk-jdk/test/hotspot/jtreg/gtest/GTestWrapper.java

Fix request approved.

Fix Request: Why? Fixing this bug is critical because without it the AArch64 build crashes on startup. What? The fix adds AArch64-specific changes which were omitted when JDK-8174962 was fixed. Risk? The risk is low because the same patch has already been successfully applied to jdk8 and passed the TCK. On jdk10 it has been tested by running java, javac and netbeans. Reviewers? It has been reviewed by Andrew Dinn and Andrew Haley. webrev (for jdk10 and jdkdev) is here: http://cr.openjdk.java.net/~adinn/8195685/webrev

This also affects JDK9.

PPC64 has related work: http://hg.openjdk.java.net/jdk/jdk10/rev/d9fcb7ba8133 , but I cannot view the bug (JDK-8191907) details either.
