Daniel Glöckner commented on ARROW-16449:
-----------------------------------------
[~lidavidm] I re-tested with the Arrow 8.0 release and java 17.0.2.
The minimal code below only works if I add {{--add-opens
java.base/java.nio=ALL-UNNAMED}} VM option. Is this expected?
{code}
import org.apache.arrow.memory.RootAllocator;
public class Arrow {
public static void main(String[] args) {
RootAllocator rootAllocator = new RootAllocator();
var buf = rootAllocator.buffer(1024);
System.out.println(buf);
}
}
{code}
