To be specific, the issue is caused by the different allocated size of a validity buffer which is N/8 from the offset buffer (N+1)*OFFSET_WIDTH. When the ration of null versus non-null values is large and the offset buffer gets filled up before the validity buffer, the `getBufferSizeFor` call will trigger the overflow error. It is quite easy to reproduce. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
