Warning

Review limit reached

@MaximPlusov, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 43 minutes

Limit details: You’ve used all 2 included reviews currently available under your plan.

You've used all free OSS reviews for now. Wait for the free limit to reset to keep reviewing this public repository.

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.

📝 Walkthrough

Walkthrough

Validation now detects thread interruption through isAbortProcessing(). Interrupted validation jobs receive JobEndStatus.CANCELLED. Traversal, deferred-rule evaluation, and assertion processing stop when cancellation is active.

Changes

Validation cancellation

Layer / File(s)	Summary
Abort processing and cancellation core/src/main/java/org/verapdf/pdfa/validation/validators/BaseValidator.java	isAbortProcessing() detects thread interruption and marks the job as cancelled. Validation traversal, deferred-rule evaluation, and assertion processing use this check.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🟡 Moderate · up to 35b48

The thread-interruption change can leave a final validation job reported as NORMAL when it was interrupted, which may misstate validation results and requires fixing or explicit owner acceptance before merge.

- Line 189: Update the loop condition in BaseValidator so isAbortProcessing() is
evaluated before checking whether objectsStack is empty, ensuring interruption
is detected after the final object is processed and the job cannot incorrectly
finish with JobEndStatus.NORMAL.
- Line 189: Update BaseValidator’s deferred-rule processing after the
objectsStack traversal to stop when isAbortProcessing() becomes true: guard the
outer deferred loop and recheck cancellation before each checkObjWithRule() call
in the inner loop, preventing further rule evaluation and progress updates after
cancellation.
