             Summary: ClassCastException during query Optimization
                 Key: TEIID-5300
                 URL: https://issues.jboss.org/browse/TEIID-5300
             Project: Teiid
          Issue Type: Bug
         Environment: Teiid 10.1
            Reporter: Mike Higgins
            Assignee: Steven Hawkins


Using Teiid 10.1 against an Oracle database, if I submit a query with exactly two bind variables such as the following:

 

SELECT "Small Molecules"."MOLREGNO", "Small Molecules"."CHEMBL_ID",

    "Small Molecules_2"."FULL_MWT", CHEMBL_20.ACTIVITIES."ACTIVITY_ID",

    CHEMBL_20.ACTIVITIES."ACTIVITY_ID", ((CHEMBL_20.ACTIVITIES."ASSAY_ID" ||

    '#') || CHEMBL_20.ACTIVITIES."STANDARD_TYPE") "ID_RESULT",

    CHEMBL_20.ACTIVITIES."STANDARD_UNITS",

    CHEMBL_20.ACTIVITIES."ACTIVITY_COMMENT",

    CHEMBL_20.ACTIVITIES."STANDARD_VALUE"

  FROM (SELECT CHEMBL_20.COMPOUND_STRUCTURES."MOLREGNO",

    SM_DICTIONARY_PRIME."CHEMBL_ID" FROM chembl_20.compound_structures INNER

    JOIN chembl_20.molecule_dictionary SM_DICTIONARY_PRIME ON (

    CHEMBL_20.COMPOUND_STRUCTURES."MOLREGNO" = SM_DICTIONARY_PRIME."MOLREGNO")

    UNION ALL SELECT CHEMBL_20.SM_REPOSITORY."MOLREGNO",

    CHEMBL_20.SM_REPOSITORY."CHEMBL_ID" FROM chembl_20.sm_repository)

    "Small Molecules" LEFT OUTER JOIN chembl_20.compound_properties

    "Small Molecules_2" ON ("Small Molecules"."MOLREGNO" =

    "Small Molecules_2"."MOLREGNO") INNER JOIN chembl_20.activities ON ((

    "Small Molecules"."MOLREGNO" = CHEMBL_20.ACTIVITIES."MOLREGNO") AND ((

    CHEMBL_20.ACTIVITIES."STANDARD_TYPE" = 'IC50') AND (

    CHEMBL_20.ACTIVITIES."ASSAY_ID" IN ('654926', '654933'))))

  WHERE ("Small Molecules"."MOLREGNO" IN (?, ?)

 

I get the following traceback, indicating that a class that does not implement Comparable is being stored in a TreeMap:
