Steven Hawkins resolved TEIID-4304.
-----------------------------------
Fix Version/s: 9.0.2
Resolution: Done
Was partially resolved in 9.0.1 (for oracle if the pushdown query contained a with clause and a subquery in the on clause, there was an exception) but fully addressed in 9.0.2.

> With the translator capability supportsSubqueryInOn false, we can still plan a query with a subquery in the on clause if non-join criteria on the inner side of a left outer join is used in the user query on clause (it is temporarily pushed out of the join and then added back in rule collapse source).
> Additionally the oracle translator should not support subquery in on for oracle 11 and earlier.
