cannot use enum type as input parameter for a query, and you cannot specify an Enum type as
a literal, this also means that there is no way to update an enum type using jpaql bulk update
------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

                 Key: OPENJPA-200
                 URL: https://issues.apache.org/jira/browse/OPENJPA-200
             Project: OpenJPA
          Issue Type: Bug
          Components: query
    Affects Versions: 0.9.7
         Environment: 0.9.7-incubating-SNAPSHOT
            Reporter: George Hongell
         Attachments: enumBugWineryTest.zip

cannot use enum as input parameter for a query, Enum cannot be used as argument in setParm,
since you also cannot specify an Enum type as a literal, this means that there is no way to
update an enum type using jpaql bulk  update
