> Sometimes, auto map join conversion unexpectedly fails to choose map join over a common
join, even if the auto map join conversion's size criterion is satisfied.
> This is caused by an integer overflow bug in the method {{compareTo}} of the class {{ConditionalResolverCommonJoin.AliasFileSizePair}}.
> The bug is triggered only if the big table size exceeds the small table size by at least
2**31 bytes.
