andygrove opened a new issue, #5706:
URL: https://github.com/apache/datafusion-comet/issues/5706
### Describe the bug
The arrow 59 migration moved `MutableArrayData::extend` to the fallible
`try_extend`, but `copy_array` turns the error straight back into a panic:
`native/core/src/execution/operators/copy.rs:42` and `:57`
```rust
mutable
.try_extend(0, 0, capacity)
.expect("extend failed due to offset overflow");
```
Both callers are already in `Result` context, so an offset overflow aborts
the JVM instead of failing the task, which is exactly what arrow deprecated
`extend` for.
### Expected behavior
`copy_array` returns `Result<ArrayRef>` and the two call sites propagate,
turning an offset overflow into a task failure.
### Additional context
Found while reviewing #5262.
