Harvesting client not compatible with servers using HTTP

[stevenferey]

Hello,

I tried to harvest an OAI server compatible with the HTTP protocol, e.g. : http://cds.unistra.fr/registry/?verb=ListIdentifiers&metadataPrefix=oai_dc

When creating a harvesting client, Dataverse seems to say that HTTP is supported:

Tested with the devleop branch, it is not possible to fill in an OAI server with the HTTP protocol :

It is however possible to declare a harvesting client with the API and fill in an OAI server with the HTTP protocol. In this case, an error is raised during harvesting :

Caused By Exception.................... java.nio.channels.UnresolvedAddressException null
StackTrace: 
java.base/sun.nio.ch.Net.checkAddress(Unknown Source)
java.base/sun.nio.ch.Net.checkAddress(Unknown Source)
java.base/sun.nio.ch.SocketChannelImpl.checkRemote(Unknown Source)

Two choices are possible:

1. Support HTTP protocol
2. Indicate that the url must start with https://...
