is it proot? usually if running java as root, you are using proot or chroot, right?
could you try outside of proot using
pkg install openjdk-21?
the reason I ask is, I that's the version of openjdk that i have put some fixes in to make it work for minecraft servers, so it is working when I test it, it should also work for you
like this
~ $ java --version
openjdk 21.0.8 2025-07-15
OpenJDK Runtime Environment (build 21.0.8)
OpenJDK 64-Bit Server VM (build 21.0.8, mixed mode)
~ $ ldd $(which java) | grep libc
libc.so => /system/lib64/libc.so
~ $ java -jar paper-1.21.8-11.jar
