AsynchronousFileChannel#close does not release and invalidate the valid FileLocks that were obtained from the channel. This is demonstrated with this simple test case:

impor java.nio.file.*;
import static java.nio.file.StandardOpenOption.*;
import java.nio.channels.*;

public class Test {
    public static void main(String[] args) throws Exception {
        Path file = Paths.get(args[0]);
        AsynchronousFileChannel ch = AsynchronousFileChannel.open(file, READ, WRITE);
        FileLock lock = ch.lock().get();
        ch.close();
        if (lock.isValid())
            throw new RuntimeException("Lock is still valid?");
    }
}

The bug is that SharedLockTable.removeAll is using lock.channel() rather than lock.acquiredBy() when checking the owner of the file lock.
