The hostname is guaranteed to be in the exception detail:

void
NET_ThrowByNameWithLastError(JNIEnv *env, const char *name,
                   const char *defaultDetail) {
    char errmsg[255];
    sprintf(errmsg, "errno: %d, error: %s\n", WSAGetLastError(), defaultDetail);
    JNU_ThrowByNameWithLastError(env, name, errmsg);
}

The "hostname" string is passed to the third parameter in the above method.
