"reserveFirstParameter" boolean parameter is being ignored in QueryParameterBindingsImpl#verifyParametersBound and this leads to
throw new QueryException( "Ordinal parameter not bound : " + parameter.getPosition() );
when the first parameter is being checked.

Initial conditions:
1. Have the following Oracle procedure:
PROCEDURE LoadValuesUsingOracleRefCursor( returning_values IN OUT SYS_REFCURSOR, some_parameters IN CLOB ) AS BEGIN ... END LoadValuesUsingOracleRefCursor;

2. Have the following named query in a hbm.xml file:
<sql-query name="load_values_from_db" callable="true">

</sql-query>

Test case:
NativeQuery query = entityManager.unwrap(Session.class).getNamedNativeQuery("load_values_from_db");
query.setParameter(2, "A_STRING_VALUE");
query.list;

Actual result: Following exception is thwrown:
Caused by: org.hibernate.QueryException: Ordinal parameter not bound : 1
at org.hibernate.query.internal.QueryParameterBindingsImpl.verifyParametersBound(QueryParameterBindingsImpl.java:213)
at org.hibernate.query.internal.AbstractProducedQuery.beforeQuery(AbstractProducedQuery.java:1425)

Sometime it's impossible to use StoredProcedureQuery with its registerStoredProcedureParameter(1, Class.class, ParameterMode.REF_CURSOR), because WebLogic 12.2.1 still uses JDBC 4.0 Oracle driver, not 4.2.
