How to solve ambiguous reference to overloaded definition in scala

I am getting the following error in scala:

ambiguous reference to overloaded definition,
both method register in trait Configurable of type (x$1: Any, x$2: <repeated...>[Class[_]])javax.ws.rs.client.Client
and  method register in trait Configurable of type (x$1: Any) javax.ws.rs.client.Client
match argument types (Object)

[ERROR]     client.register(ClientFilter.getFilter().asInstanceOf[Object])

Shouldn't asInstance[Object] inform the compiler which version of jersey client register to use? Here's the code:

val client: Client =
      ClientBuilder.newBuilder()
        .build();
 client.register(ClientFilter.getFilter().asInstanceOf[Object])

ClientFilter.getFilter() is an instance of ClientRequestFilter

You'll need a Java class to do the dispatch for you, due to this issue not getting resolved in favor of my PR, which added -Yno-java-tupling to do what you expect. Hopefully the workarounds will be temporary, and won't be necessary once overload resolution precedes autotupling, as described in a comment on the ticket.
