> Line numbers are shifted due to logging; the NPE is at
> {noformat}
> hashMapRowGetters = new ReusableGetAdaptor[mapJoinTables.length];
> {noformat}
> So looks like mapJoinTables is null.
> I added logging to see if they could be set to null from cache, but that
> doesn't seem to be the case.
> Looks like initializeOp is not called.
