Got a error: UnknownColumnException: Unknown column. Maybe a bug ?

Question

My have a SQL kind of like this:

select SUM(IF(temp.sub_type = 2 AND temp.id IS NOT NULL, 1, 0)) as re
from (select *
      from A a
               join B b on a.s_id = b.s_id
      where a.is_del = 0
        and not EXISTS(select null from C c  join D d on c.r_id = d.r_id and c.s_id = a.s_id)
) temp

The SQL can be run successfully with normal JDBC, but after using Shardingsphere JDBC, I got one error bellow:

Caused by: org.apache.shardingsphere.infra.exception.UnknownColumnException: Unknown column 'a.s_id' in 'on clause'.

Then I debugged the code, and found something maybe wrong in the red circle bellow :

And I don't understand why passing 'Collections.emptyMap()' into method 'result.setCondition' here:

result.setCondition(ExpressionSegmentBinder.bind(segment.getCondition(), SegmentType.JOIN_ON, statementBinderContext, tableBinderContexts, Collections.emptyMap()));

Is this a bug or my SQL is wrong ?
