Hi,

You are using the custom resolver API for Java. This API is available only 
in limited gRPC languages, like Java/Go, but not Core-based languages, like 
C++/Python/Ruby/C#/ObjC/PHP.

You may need to inject the candidate addresses to DNS backends. Many DNS 
providers / cloud providers offer this feature.

Locally, depending on the OS, there should be ways to define name -> IP 
resolutions, like /etc/hosts.
