Paul Rogers commented on DRILL-6343:
------------------------------------
The bit vector is deprecated and likely badly broken. We are using
`UInt1Vector` in place of `BitVector`.
> bit vector copyFromSafe is not doing realloc

> bit vector copyFromSafe simply returns false when asked to copy to an index
> greater than it's capacity. It should do realloc if needed and copy correctly.
> This bug is very subtle and shows up as random wrong result. allocateNew for
> bit vector allocates 4096 bytes initially and if we do copyFromSafe to any
> index greater than that, we basically do not do any copy, but just return
> false.
