I have two instances of a DTO with identical field values:

ConnectionInfo [_localIp=IpAddress [_ipv4Address=Ipv4Address [_value=127.0.0.1], _value=[1, 2, 7, ., 0, ., 0, ., 1]], _localPort=PortNumber [_value=62679], _remoteIp=IpAddress [_ipv4Address=Ipv4Address [_value=127.0.0.1], _value=[1, 2, 7, ., 0, ., 0, ., 1]], _remotePort=PortNumber [_value=16640], augmentation=[]]
ConnectionInfo{getLocalIp=IpAddress [_ipv4Address=Ipv4Address [_value=127.0.0.1], _value=[1, 2, 7, ., 0, ., 0, ., 1]], getLocalPort=PortNumber [_value=62679], getRemoteIp=IpAddress [_ipv4Address=Ipv4Address [_value=127.0.0.1], _value=[1, 2, 7, ., 0, ., 0, ., 1]], getRemotePort=PortNumber [_value=16640], augmentations={}}

The first is created with a Builder, the second comes back from the datastore.

I have a Map clients that has a key from the one build with the builder.

clients.get(<the one from the datastore read>) returns null in spite of
there being an instance with exactly the same field values.

Also... apparently they have different toString() results... weird.
