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.

For JNU_ThrowByNameWithLastError then the third parameter is the 
default/fallback, only used when the error cannot be translated. As I 
said, it's not a big deal as you are only using it for the WSATRY_AGAIN 
case.
