I try to perform query over over some table data in Java using Calcite. I try

select distinct tbl.col1 , tbl.col2 from infoset.SUBEKT tbl order by col1 asc
nulls last , col2 asc nulls last{code}
And the following exception occurs

{code}
The error occurs because col1 has some rows with null values. If I order only
by col1 or col2, all works well.
