--------------------------------------------
Summary: camel-aws2-sqs: create queue logic is susceptible to
TOC/TOU errors
Key: CAMEL-15833
URL: https://issues.apache.org/jira/browse/CAMEL-15833
Project: Camel
Issue Type: Bug
Components: camel-aws2
Affects Versions: 3.6.0, 3.4.4
Reporter: Otavio Rodolfo Piske
The AWS v2 SQS component has a time-of-check / time-of-use bug when creating
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.
