Hi Martijn, I somehow missed this email, sorry about that and for the late reply.

Merging the code would help greatly if the aim is to eventually use the upstream tarballs. As for keeping in sync, aarch64 has been doing quite a good work recently, releasing very closely with upstream. > As an FYI - the 'Official' AArch64 port for OpenjDK 8 (jdk8u) is actually > https://hg.openjdk.java.net/aarch64-port/jdk8u-shenandoah > > I'm not sure if this is where Debian was building from for that platform?

It would be great if they could get their releases out faster, similar to what aarch64 has done - moving from weeks to a couple days or less. Usually most openjdk-8 packages have been released with an aarch32 hotspot that was 1 or 2 releases behind, with only hotspot security updates on top (if there's any), thus forsaking any hotspot fixes from newer releases. Keep in mind that OpenJDK updates in stable Debian/Ubuntu releases are usually considered security updates, so this approach is just fine just not optimal. It also allowed us to provide a faster hotspot for the armhf users, speed up our build, and being able to run the whole testsuites which was not possible with the ZeroVM builds.
