Dear maintainer, upstream patch for OpenJDK 9 is reviewed and awaiting Oracle's approval to be merged. Backport to OpenJDK 8 will be requested in the due time but is trivial. Thanks.
Hi Andrew, Please, find the patches in question already backported to 8u upstream: http://hg.openjdk.java.net/jdk8u/jdk8u-dev/rev/fddd627ea372 http://hg.openjdk.java.net/jdk8u/jdk8u-dev/jdk/rev/80927e772b9a Thanks.
Looks like they're already in the aarch64/jdk8u repo too: http://hg.openjdk.java.net/aarch64-port/jdk8u/rev/7dc91fd23728 http://hg.openjdk.java.net/aarch64-port/jdk8u/jdk/rev/7c54c63ba667 So we'll pick them up anyway.
