Review Comment:
> But it would be the only way to avoid this memory leak.
Why that is only way to avoid memory leak. Now the created one value buffer
only has one ref count for imported side. And it will be decreased and release
the buffer once the imported side finishes its usage.
Is any mechanism in Java Arrow that can cause it memory leak?
