Looks like it is a regression : https://github.com/apache/iceberg/pull/4859
It seems we tried fixing it long time back but didn't fix properly.

Yeah, I'd probably start with making this https://github.com/apache/iceberg/blob/main/spark/v3.5/spark/src/test/java/org/apache/iceberg/spark/actions/TestRemoveOrphanFilesAction.java#L273 a `ConcurrentHashMap.newKeySet();`. Even though the implementation inserts unique elements (file paths), there are no thread safety guarantees on normal hash sets. I think it's possible there could be some weird corruptions of internal state on the underlying table/buckets in the set which lead to missing elements.
