How to implement a custom Auth Provider

[Enrico Olivelli]

Hi,
I'm going to implement a custom AuthProvider for BookKeeper, I have
come to a showstopper:
ClientAuthProvider.Factory depends on Protobuf ExtensionRegistry,
which is shaded inside the BooKeeper JAR

A custom provider will look like the code below, this is not good,
because my code needs to depend on an "hidden" dependency of BK.

I can file a JIRA and propose a fix, but any fix need to break
compatibilty with existing custom Providers (But I assume that no
implemention can actually exist, outside a fork of BookKeeper)

What do you think ?

This is an example

public class CustomProvider implements ClientAuthProvider.Factory {

    @Override
    public void init(ClientConfiguration cc,
bk-shade.com.google.protobuf.ExtensionRegistry er) throws IOException
{
        throw new UnsupportedOperationException("Not supported yet.");
//To change body of generated methods, choose Tools | Templates.
    }

    @Override
    public ClientAuthProvider newProvider(InetSocketAddress isa,
BookkeeperInternalCallbacks.GenericCallback<Void> gc) {
        throw new UnsupportedOperationException("Not supported yet.");
//To change body of generated methods, choose Tools | Templates.
    }

    @Override
    public String getPluginName() {
        throw new UnsupportedOperationException("Not supported yet.");
//To change body of generated methods, choose Tools | Templates.
    }

}
