com.google.cloud:google-cloud-pubsub (version 1.126.1) does not honour message ordering

[abclabs-jon]

Expected Behavior

Messages published with an ordering key to a single region should be handled in order for subscriptions with message ordering enabled.

Actual Behaviour

After upgrading Micronaut from 3.8.10 to 4.3.7, subscribers started receiving messages out of order.

The root cause seems to be in com.google.cloud:google-cloud-pubsub: googleapis/java-pubsub#1889

io.micronaut.gcp:micronaut-gcp-pubsub:5.4.1 uses com.google.cloud:google-cloud-pubsub:1.126.1, which has the bug. Forcing an upgrade of that solved the issue for us:

    constraints {
        implementation("com.google.cloud:google-cloud-pubsub:1.127+") {
            because("https://github.com/googleapis/java-pubsub/issues/1889")
        }
    }

Steps To Reproduce

See googleapis/java-pubsub#1889

This should already be resolved in micronaut-platform 4.4.0, which brings in micronaut-gcp-pubsub 5.5.0, which brings in google-cloud-pubsub 1.128.0, which contains the fix for this issue.
