Steven Hawkins commented on TEIID-5345:
---------------------------------------

This can still be reproduced on master with a small example:

select pm1.g2.e1 from pm1.g2 inner join /*+ makedep */ (select 1 as x, 'a' as y, e1 from pm1.g1 union all select 2, 'b', e1 from pm2.g1) v on y = pm1.g2.e1 and x = pm1.g2.e2

> Select without criteria returns - select * from table, If adding criteria on col_CD it fails with ClassCastException[1].  I assume it's because on some sources the col_CD is derived by a case statement[2].
