An example which demonstrates how to narrow down the return type of a Java method in a new version of a Java library, using Bridger to keep backwards compatibility.
In service-1.0, there's a method Number SomeService::getSomeNumber().
In service-2.0, this return type is narrowed down to Long.
Consequently, the integration test in integration-test fail,
as it uses client, as built against service-1.0, together with service-2.0.
Switch to version 3.0.0 to make the test pass.
This works as service-3.0 injects a bridge method which returns Number.
