@Sunjeet it seems to be one/all of these three calls to putOrderedLong() in FixedLengthElementArray that's causing the crash I'm seeing at least: https://github.com/Netflix/hollow/blob/master/hollow/src/main/java/com/netflix/hollow/core/memory/encoding/FixedLengthElementArray.java#L194-L200
ARM doesn't support reading/writing unaligned values - the solution I believe would be replacing those calls with plain old accesses to the array. It would negatively impact performance, though, so ideally we could somehow use the existing path on platforms that support it, and the new path only on platforms that do not
I'd love to see anything you're willing to share about your testing on ARM in addition to this PR Netflix/hollow#503 though :)
I'll try to spend some time this weekend hacking on this to see if I can get something together.
sun.misc.Unsafe(neither building from console nor from IntelliJ works). I currently have JDK 11 and JDK 15 installed on my machine. Can someone point me towards change I need to make to build the project?
