davsclaus opened a new pull request, #24952:
URL: https://github.com/apache/camel/pull/24952
## Summary
_Claude Code on behalf of davsclaus_
Fixes two issues from the CAMEL-24170 data format review in
`camel-univocity-parsers`:
- **H9 — ThreadLocal header cross-thread NPE:** `HeaderRowProcessor` stores
headers in a `static ThreadLocal`. When `lazyLoad=true` and `asMap=true`, the
lazy `MapRowIterator` is returned as the exchange body. If consumed on a
different thread (parallel split, seda, kafka), `getHeaders()` reads from the
wrong ThreadLocal slot and returns null, causing an NPE. Fixed by capturing
headers eagerly in `MapRowIterator`'s constructor (on the parsing thread) as a
`final String[]` field.
- **H10 — Closeable iterator:** `RowIterator` now implements `Closeable`
with `close()` calling `parser.stopParsing()`, enabling callers to explicitly
release the underlying input stream. Added a documentation note about the
lazy-load resource management contract.
## Test plan
- [x] New `UniVocityCsvLazyLoadAsMapTest` with 3 tests:
- `shouldUnmarshalLazyAsMap` — lazy + asMap on same thread
- `shouldUnmarshalLazyAsMapOnDifferentThread` — lazy + asMap consumed via
seda (cross-thread, validates H9 fix)
- `shouldCloseIteratorOnCompletion` — verifies iterator implements
Closeable
- [x] All 118 existing univocity-parsers tests pass
