> Key: CAMEL-15064
> URL: https://issues.apache.org/jira/browse/CAMEL-15064
> Project: Camel
> Issue Type: Bug
> Components: camel-google-pubsub
> Affects Versions: 3.2.0
> Environment: * macOS 10.15.4
> * OpenJDK 11.0.6 2020-01-14
> * I've been able to reproduce the issue on Ubuntu 16, same JDK
> Reporter: Jean-Pierre Matsumoto
> Assignee: Omar Al-Safi
> Priority: Major
> Fix For: 3.4.0
>
>
> 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:
> {code:java}
> @Component
> public class SimplePubsubRouteBuilder extends RouteBuilder {
> @Override
> public void configure() throws Exception {
> from("google-pubsub://project-id:subs-name")
> .to("log:myLog?showHeaders=true");
> }
> }{code}
> 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.
