# Build and run java tests under aarch64 image.
# To be able to run this docker container on x64 machine, one needs to have
# qemu-user-static properly registered with binfmt_misc.
# The most important flag binfmt_misc flag we need is "F" (set by "--persistent yes"),
# which allows the qemu-aarch64-static binary to be loaded eagerly at the time of registration with binfmt_misc.
# That way, we can emulate aarch64 binaries running inside docker containers transparently, without needing the emulator
# binary to be accessible from the docker image we're emulating.
# Note that on newer distributions (such as glinux), simply "apt install qemu-user-static" is sufficient
# to install qemu-user-static with the right flags.
# A note on the "docker run" args used:
# - run docker container under current user's UID to avoid polluting the workspace
# - set the user.home property to avoid creating a "?" directory under grpc-java
