[jira] [Created] (CALCITE-1408) AccessorImpl throws RuntimeException when conversion is impossible

Laurent Goujon created CALCITE-1408:
---------------------------------------

             Summary: AccessorImpl throws RuntimeException when conversion is impossible
                 Key: CALCITE-1408
                 URL: https://issues.apache.org/jira/browse/CALCITE-1408
             Project: Calcite
          Issue Type: Bug
          Components: avatica
            Reporter: Laurent Goujon


{{AccessorImpl}} relies on {{cannotConvert(String)}} method to throw a exception when conversion is not possible between the accessor data type, and what the user requested.

The exact class type of the exception is {{RuntimeException}} which is very generic, and not easy for the user to catch, unlike more specific types. Moreover JDBC drivers usually throws a {{SQLException}} instances for these kind of exceptions, which is likely what users are expecting.
