---------------------------------
Resolution: Fixed
> camel-salesforce - streamQueryResult iterator hangs the route thread forever
> when queryMore fails
> -------------------------------------------------------------------------------------------------
>
> Key: CAMEL-24155
> URL: https://issues.apache.org/jira/browse/CAMEL-24155
> Project: Camel
> Issue Type: Bug
> Components: camel-salesforce
> Reporter: Federico Mariani
> Assignee: Claus Ibsen
> Priority: Critical
> Labels: review-2026-07
> Fix For: 4.22.0
>
> Attachments: QueryResultIteratorErrorTest.java
>
>
> Found during a code review of camel-salesforce on main (4.22.0-SNAPSHOT).
> In {{QueryResultIterator.next()}} (internal/processor, lines ~60-94), the
> page-fetch callback passed to {{restClient.queryMore(...)}} completely
> ignores its {{exception}} parameter. On any failure,
> {{AbstractClientBase.doHttpRequest}} invokes the callback with {{response ==
> null}} plus a {{SalesforceException}}; {{objectMapper.readValue(null, ...)}}
> then throws inside the Jetty worker thread, so {{latch.countDown()}} — which
> is not in a finally block — is never reached, and {{latch.await()}}, which
> has *no timeout*, blocks the consuming route thread forever. The same hang
> occurs when {{readValue}} throws {{IOException}} or a page unexpectedly
> contains zero records.
> *Failure scenario*: {{streamQueryResult=true}} query over a large result set;
> while the route iterates the returned Iterator, the session expires, the
> network blips, or Salesforce returns any non-2xx for the {{nextRecordsUrl}}
> fetch. The route thread blocks permanently inside {{next()}}, the exchange
> never completes, and the only trace is an uncaught-exception log on a Jetty
> worker thread.
> *Reproducer*: attached {{QueryResultIteratorErrorTest.java}} (unit test, goes
> under
> {{components/camel-salesforce/camel-salesforce-component/src/test/java/org/apache/camel/component/salesforce/internal/processor/}}).
> It simulates the asynchronous callback invocation exactly as production does
> (callback fired from a separate thread with a null response and a
> SalesforceException) and fails by preemptive timeout because {{next()}} never
> returns.
> *Suggested fix*: in the callback, check {{exception != null}} (and wrap parse
> failures), store the error in a holder, always {{countDown()}} in a finally
> block, and rethrow the stored error from {{next()}} on the iterating thread.
> _This issue was researched and filed by Claude Code (AI) on behalf of
> Federico Mariani (fmariani). Full findings document from the review is
> attached to the umbrella issues._
