Let me try to summarize the issue: 1. Java Arrow uses empty buffer internally for offset buffer (valid, for historical reason). For C Data Interface, it is not valid. We are going to send one value (zero) buffer at the moment. 2. Currently the empty buffer sent by Java Arrow would be NULL pointer if unsafe allocator is used. It is because UNSAFE `allocateMemory` API returns a NULL pointer for zero bytes allocation. -- This is an automated message from the Apache Git Service.
