Executing query in JBoss DV with a recursive WITH clause results in "java.lang.ClassCastException: org.teiid.query.sql.lang.Query cannot be cast to org.teiid.query.sql.lang.SetQuery"

Issue

• executing a query with a recursive WITH clause results in a ClassCaseException like the example below:

ERROR [org.teiid.PROCESSOR] (Worker1_QueryProcessorQueue29) TEIID30019 Unexpected exception for request juY1MrNVs8vD.7: java.lang.ClassCastException: org.teiid.query.sql.lang.Query cannot be cast to org.teiid.query.sql.lang.SetQuery
