viirya opened a new issue #1333: URL: https://github.com/apache/arrow-rs/issues/1333
**Describe the bug** `ArrowArray::try_from_raw` now uses `Arc::from_raw` to construct the two pointers to the C Data Interface (ArrowArray and ArrowSchema) back to the structs. But the two pointers could be from other language runtime (e.g. JVM). We've been using the ffi API to pass Arrow Arrays from JVM to Rust. Sometimes we see fatal error reported at JVM (`SIGILL`). After digging it deeper, we found that sometimes `Arc::from_raw` on the pointers gives a `Arc` pointer with strong reference count reaching the maximum limit. As the pointer is from JVM, it is not produced by `Arc::into_raw`, the offset calculation in `Arc::from_raw` simply doesn't work and can get into wrong values for the `strong` value in `ArcInner`. I think that `ArrowArray::try_from_raw` should not assume the pointers are from `Arc`. They should be considered as just raw pointers to the C Data Interface. **To Reproduce** Steps to reproduce the behavior: **Expected behavior** A clear and concise description of what you expected to happen. **Additional context** Add any other context about the problem here. -- This is an automated message from the Apache Git Service.
