{IgniteServices#service(String name)} returns direct reference in the
current implementation.
So, class casting should work for your example:
((MyServiceImpl)ignite.services().service(“myService”)).bar();
It is safer to use an interface instead of an implementation, there is no
guarantee that in future releases direct link will be returned, a service
instance might be wrapped for monitoring for example.
