------------------------------------------------------------------

                 Key: HHH-2903
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2903
             Project: Hibernate3
          Issue Type: Patch
          Components: core
    Affects Versions: 3.2.5
            Reporter: Marcus Brito
         Attachments: report-wrong-parameter-type.diff

The attached patch modifies NamedParameterSpecification and PositionalParameterSpecification to catch any ClassCastExceptions thrown while binding parameters, and rethrow them as QueryParameterExceptions, including a detailed error message containing the parameter name or position that failed to bind, and the (most probably) expected type the parameter should have received.
