> FileDataSourceV2.attachFilePath uses NonFatal pattern matching which does not match fatal errors like OutOfMemoryError. When OOM occurs during file reading (e.g., large Parquet row groups), the incomplete match causes a scala.MatchError that masks the original error.
> The fix adds a catch-all case to rethrow fatal errors directly, preserving the original error for proper JVM-level handling.
