More fun with that.

working system, glibc 2.34, on any kernel

mkdir /test/
rsync -avPH / /test/ --exclude /test/ --exclude /proc --exclude /sys
mount /proc /test/proc -o bind
chroot /test/; java -version - hangs at some retry

mkdir -p /test/sys/devices/system/cpu
chroot /test/; java -version - no hangs
(so proc is mounted but /sys is not; just dir exists)
