Yes, that factory was only necessary due to some caching impl
requirements, which went away in v3, so the factory became unnecessary
as well.

The MCR now directly takes a RoleDescriptorResolver, rather than a
MetadataResovler (new name for MetadataProvider).  The RDR wraps a
MetadataResolver.

All of those are now InitializableComponents, so have to call
initialize() before use.

So you'd do something like this:

// Whatever concrete impl of metadata provider you like
MetadataResolver metadataResolver = .... ;
       
BasicRoleDescriptorResolver roleDescriptorResolver = new
BasicRoleDescriptorResolver(metadataResolver);
roleDescriptorResolver.initialize();
       
MetadataCredentialResolver metadataCredentialResolver = new
MetadataCredentialResolver();
metadataCredentialResolver.setRoleDescriptorResolver(roleDescriptorResolver);
metadataCredentialResolver.initialize();
