        JDK-8303942 introduced a bug in os::write() in os.cpp for handling partial write:
        ```
        buf = (void *)((char *)buf + nBytes);
        ```
        should be

        ```
        buf = (void *)((char *)buf + res);
        ```

        We observed that in JDK 21, heap dump corruption observed in JDK-8303937 happens again when writing to a socket or pipe.
