murali-db opened a new issue, #14564:
URL: https://github.com/apache/iceberg/issues/14564
### Apache Iceberg version
1.10.0 (latest release)
### Query engine
None
### Please describe the bug 🐞
## Bug Description
`RESTFileScanTaskParser.fromJson()` throws `NoSuchElementException` when
parsing responses with empty `delete-file-references` arrays.
## Location
`core/src/main/java/org/apache/iceberg/rest/RESTFileScanTaskParser.java:90`
## Root Cause
```java
if (jsonNode.has(DELETE_FILE_REFERENCES)) {
List<Integer> indices = JsonUtil.getIntegerList(DELETE_FILE_REFERENCES,
jsonNode);
Preconditions.checkArgument(
Collections.max(indices) < allDeleteFiles.size(), // ← LINE 90:
Crashes if indices is empty
"Invalid delete file references: %s, expected indices < %s",
indices,
allDeleteFiles.size());
```
`Collections.max() throws NoSuchElementException when called on an empty
list.`
## Reproduction
1. Use Iceberg REST catalog with server-side scan planning
2. Create a table with data files but no delete files
3. Call plan table scan endpoint
4. Server returns valid JSON with "delete-file-references": []
5. Parser crashes with NoSuchElementException
## Expected Behavior
Empty delete-file-references arrays should be valid (no delete files to
reference).
If confirmed as an issue, I can contribute a bug fix for this.
