Description

Line numbers are shifted due to logging; the NPE is at

        hashMapRowGetters = new ReusableGetAdaptor[mapJoinTables.length];

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.
