描述
### Describe the bug, including details regarding any error messages, version, and platform.
We see memory alignment error when passing arrays allocated using Java arrow to Rust arrow. This is due to strict memory alignment requirement (https://github.com/apache/arrow-rs/issues/4431) at Rust side. I have described the issue there.
So as it looks like it is impossible to access unaligned memory pointers at Rust side. I'm wondering if we could change Java arrow on memory allocation? Could we allocate memory with alignment for arrays in Java arrow so it could be safely sent to other arrow ecosystems?

貢獻指南
研究方向
首先檢視 Java 元件的記憶體配置路徑,以及連結的 arrow-rs issue 4431。判斷 Java Arrow 是否能為與 Rust Arrow 共用的陣列提供所需的對齊方式,並定義將該 issue 視為已解決所需的配置行為與驗證。
