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 (apache/arrow-rs#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?
