Hey @erikj79, thank you so much for giving it a try!

Hmm, that's interesting. What environment is that exactly? What `configure`
line are you using there? We have tested on
such a system: $ cat /etc/issue
Ubuntu 19.10 \n \l
$ bash configure --with-boot-jdk=/home/beurba/work/jdk-16+13 --with-jtreg
$ make clean CONF=linux-aarch64-server-release
$ make images JOBS=255 LOG=info CONF=linux-aarch64-server-release
$ ./build/linux-aarch64-server-release/images/jdk/bin/java
-XshowSettings:properties -version 2>&1 | grep aarch64
java.home =
/home/beurba/work/jdk/build/linux-aarch64-server-release/images/jdk
os.arch = aarch64
sun.boot.library.path =
/home/beurba/work/jdk/build/linux-aarch64-server-release/images/jdk/lib

Yes. As far as I understand, the problem is that `fixpath.exe` isn't built
properly when doing cross-compiling on
Windows targets (as it hasn't been a thing so far). We use a workaround
internally
https://gist.github.com/lewurm/c099a4b5fcd8a182510cbdeebcb41f77 , but a proper
solution is under discussion on
build-dev:
