>> @jianglizhou Thank you for your assistance in figuring out the problem. I guess I throw out too much code from the hermetic-java-runtime branch when trying to minimize the changes to only build-related stuff. The jimage changes were so busy so I probably ignored them a bit too much.

As I said before, I think we really ought to take a step back, consider the wider picture, and refactor the way we interact with internal native libraries. Determining how to handle `_sun_boot_library_path` for static builds are definitely part of that work.
