    1063       if (os::fork_and_exec(cmd) < 0) {
    1064         out.print_cr("os::fork_and_exec failed: %s (%d)", strerror(errno), errno);

    This --^ establishes pre JDK-8219677 8u backport code. In JDK 9+ line
    1063 changed with JDK-6985422 which is not in JDK 8u.
    
    Looks good.
    
    Thanks,
