Priority: ⬇️ Low Estimated code review effort: 2 (Simple) | ~10 minutes Change: Bug fix · Severity of issue fixed: Low Merge Risk: 🔴 Critical · up to As it stands, the framework core does not build: a method in the event processor is missing a brace, so compilation fails for the library and everything depending on it. Additionally, an earlier concern remains open where an event arriving after a delete can be reported as triggering an upcoming reconciliation while being discarded during successful delete cleanup. Both should be addressed before merging. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

- The new API wording promises that this condition holds regardless of success or failure, but a successful delete-event execution is terminal:
eventProcessingFinishedcleans up at lines 309–311 instead of scheduling a follow-up, even when a post-delete event is present. Please qualify this statement to the retry-enabled failure path so callers are not told thattruealways means another reconciliation will run.
* <p>This holds regardless of whether the current reconciliation succeeds or throws, so with
* {@link ControllerConfiguration#triggerReconcilerOnAllEvents()} it also covers an event that
* arrived after a delete event.
operator-framework-core/src/main/java/io/javaoperatorsdk/operator/processing/event/EventProcessor.java:520
- This documentation overstates the success-path behavior: when the current
ExecutionScopeis a delete event,eventProcessingFinishedtakes the cleanup branch at lines 309–311 and does not submit another reconciliation, even if an additional post-delete event is present. The additional state is used to trigger an immediate follow-up inhandleRetryOnException, not unconditionally after both success and failure; please narrow this wording to the retry/failure case or update the success path if that is the intended contract.
* reconciliation right after the current one, both when it succeeds (see {@link
* #eventProcessingFinished}) and when it fails (see {@link #handleRetryOnException}), so it has
* to be reported as imminent too.
operator-framework-core/src/main/java/io/javaoperatorsdk/operator/processing/event/EventProcessor.java:520
- This branch makes
isNextReconciliationImminent()report true for an additional event while the current execution is a delete execution, buteventProcessingFinishedchecksexecutionScope.isDeleteEvent()first and callscleanupForDeletedEvent, removing the state before the later pending-event branch can submit a reconciliation. Thus a successful delete reconciliation can cause this newly reported event to be dropped, leaving callers that skip work based on this flag with no follow-up reconciliation. Adjust the successful-completion path (and add a regression test) so the additional event is retained and dispatched, or do not report it as imminent in this case.
* An event that arrives after a delete event is tracked in a dedicated state, so {@link
* ResourceState#eventPresent()} alone does not cover it. Such an event triggers a new
* reconciliation right after the current one, both when it succeeds (see {@link
* #eventProcessingFinished}) and when it fails (see {@link #handleRetryOnException}), so it has
* to be reported as imminent too.

The test released the blocked reconciler right after the update call returned, but the update event still had to travel back through the informer. When the reconciliation failed before the event was registered, the framework treated the failure as a plain retry (consuming the last attempt) instead of instantly re-triggering because of a superseding event, so only 4 instead of 5 reconciliations happened. Wait for isNextReconciliationImminent() in the reconciler, which reflects exactly the state the framework checks after the reconciliation fails and cannot be unset while it is in progress. The reconciliation triggered by the superseding event reuses the same retry execution, so its attempt count is still 1 and it would enter the wait too, this time never being released; guard the wait with a one-shot flag. Also fix the isWaiting() assertion that had no terminal assertion and was therefore a no-op.
Context.isNextReconciliationImminent() only checked ResourceState.eventPresent(), which is false for ADDITIONAL_EVENT_PRESENT_AFTER_DELETE_EVENT. In triggerReconcilerOnAllEvents mode that state does trigger a new reconciliation right after the current one, both on the success path (eventProcessingFinished) and on the failure path (handleRetryOnException), so the method contradicted its own contract and a reconciler could skip a status update that nothing else would produce. Extract the condition handleRetryOnException already computed into a shared helper and use it for isNextReconciliationImminent() too, so the two cannot drift apart again. The condition is the one that holds regardless of whether the current reconciliation succeeds or throws; documented on Context.
