Ruben Q L updated CALCITE-6600:
-------------------------------
Description:
AggregateJoinTransposeRule can throw ArrayIndexOutOfBoundsException when
applied on a SemiJoin, because it creates a mapping containing only 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
