Claus Ibsen updated CAMEL-24196:
--------------------------------
Fix Version/s: 4.22.0
> camel-aws2-sqs - QueueDoesNotExist swallowed, thread pool leak, and batch
> chunking
> ----------------------------------------------------------------------------------
>
> Key: CAMEL-24196
> URL: https://issues.apache.org/jira/browse/CAMEL-24196
> Project: Camel
> Issue Type: Bug
> Components: camel-aws
> Reporter: Claus Ibsen
> Assignee: Claus Ibsen
> Priority: Minor
> Labels: review-2026-07
> Fix For: 4.22.0
>
>
> Split from CAMEL-24157 (medium-severity findings, group 3).
> Three remaining SQS findings that require careful design work:
> *1. QueueDoesNotExistException silently swallowed when maxMessagesPerPoll >
> 10*
> {{Sqs2Consumer:597,655-671}} — When {{maxMessagesPerPoll > 10}}, parallel
> polling sends multiple requests. The first thread to catch
> {{QueueDoesNotExistException}} calls {{firePollingError}} (registering 1
> error), but remaining threads see {{isQueueMissing()}} and return empty
> without firing errors. Error propagation at line 597 requires {{errorCount()
> == numberOfRequestsPerPoll}}, which never matches (1 ≠ N). The missing-queue
> error is silently swallowed and the consumer returns empty forever. Works
> correctly when {{maxMessagesPerPoll <= 10}}.
> *2. Consumer stop/start cycle leaks PollingTask thread pool*
> {{Sqs2Consumer:302-363,578-587}} — {{doStart()}} unconditionally creates a
> new {{PollingTask}} with a new {{ExecutorService}} thread pool. Cleanup only
> happens in {{doShutdown()}}, not {{doStop()}}. Each route stop/start cycle
> leaks the previous thread pool.
> *3. sendBatchMessage lacks 10-entry chunking*
> {{Sqs2Producer:119-174}} — All entries collected into a single
> {{sendMessageBatch()}} call. SQS hard-limits batches to 10 entries; 11+
> throws {{TooManyEntriesInBatchRequestException}}. Empty iterables and
> non-String elements are also unhandled.
> *Fix approach:*
> - #1: Propagate error when any parallel request gets QueueDoesNotExist, not
> only when all fail
> - #2: Add {{doStop()}} override to shut down the PollingTask thread pool and
> cancel the visibility extender
> - #3: Chunk entries into groups of 10 before calling {{sendMessageBatch()}};
> validate inputs
