xhxaidi opened a new issue, #18505:
URL: https://github.com/apache/iceberg/issues/18505
### Apache Iceberg version
main (development)
### Query engine
None
### Please describe the bug 🐞
`RESTFileScanTaskParser.fromJson` checks that `delete-file-references`
indices are
below the number of delete files, but never checks the lower bound. A server
response with `"delete-file-references": [-1]` passes the check and fails at
`allDeleteFiles.get(-1)` with `IndexOutOfBoundsException: index (-1) must
not be negative`,
which does not point at the malformed response.
Expected: an `IllegalArgumentException` like the existing out-of-range check
("Invalid delete file references: ...").
Repro: pass a plan response whose file scan task has
`"delete-file-references": [-1]`
to `PlanTableScanResponseParser.fromJson`.
