[Steven Hawkins (JIRA)]

     [ https://issues.jboss.org/browse/TEIID-4304?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Steven Hawkins resolved TEIID-4304.
-----------------------------------
    Resolution: Done


Added a check in determining if a join is acceptable to look at child select nodes - and to later mark them as evaluatable if needed.  Also updated the oracle translator.

> 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.
