it a restriction with LOB's.
quoting the doc's

LOBs are not allowed in GROUP BY, ORDER BY, SELECT DISTINCT, aggregates and     JOINS. However, UNION ALL is allowed on tables with LOBs. UNION, MINUS, and     SELECT DISTINCT are allowed on LOB attributes if the object type has a MAP     or ORDER function.
