> Project: Camel
> Issue Type: Bug
> Components: camel-aws2
> Affects Versions: 3.4.4, 3.6.0
> Reporter: Otavio Rodolfo Piske
> Assignee: Otavio Rodolfo Piske
> Priority: Major
>
> The AWS v2 SQS component has a time-of-check / time-of-use bug when creating
> queues. Currently, the code [checks if the queue exists and, if not, creates
> it|https://github.com/apache/camel/blob/828a99183f08b4ea609a765837c668b9aba21faa/components/camel-aws2-sqs/src/main/java/org/apache/camel/component/aws2/sqs/Sqs2Endpoint.java#L192].
> However, if another application or thread creates the queue in between the
> check and the creation, the component fails and the startup is aborted.
>
> IMHO, a better approach would be to - in case of an exception - check if the
> queue hasn't been created before aborting.
