Description

With Camel 3.2.0, my route does not receive the messages from Google Pubsub. The exact same route works well if I downgrade to 3.1.0.

I've created following test case to reproduce easily the issue:

@Component
public class SimplePubsubRouteBuilder extends RouteBuilder {
  @Override
  public void configure() throws Exception {
    from("google-pubsub://project-id:subs-name")
      .to("log:myLog?showHeaders=true");
  }
}

Result with Camel 3.2.0: nothing happens, no errors even with DEBUG log
level.

Result with Camel 3.1.0: error 404 as expected since Pubsub subscription
path is invalid.

I've tried to fix the issue myself with no success. But by tracing with debugger, I think the issue is because of bad version of Guava library.
