> AggregateJoinTransposeRule can throw ArrayIndexOutOfBoundsException when
> applied on a SemiJoin, because it creates a mapping containing the Join's
> field count (which in case of a SemiJoin is just the LHS field count), and
> said mapping is used to process the (Semi)Join condition, which can contain
> references to the RHS fields.
> The exception looks like:
> {noformat}
> Index 2 out of bounds for length 2
> java.lang.ArrayIndexOutOfBoundsException: Index 2 out of bounds for length 2
