We will see warn messages:

WARNING: A restricted method in java.lang.System has been called
WARNING: java.lang.System::loadLibrary has been called by net.jpountz.util.Native in an unnamed module (file:/tools/sjsonnet.jar)
WARNING: Use --enable-native-access=ALL-UNNAMED to avoid a warning for callers in this module
WARNING: Restricted methods will be blocked in a future release unless native access is enabled

You can disable this warning by using
JAVA_OPTS="--enable-native-access=net.jpountz.util" ./tools/sjsonnet.jar ....

This is definitely an annoyance, so I'll keep this open for now.
