Serdyn du Toit created OPENJPA-2407:
---------------------------------------

             Summary: Errors using MySql not present using HSqlDb (build-time enhancement
and executing query)
                 Key: OPENJPA-2407
                 URL: https://issues.apache.org/jira/browse/OPENJPA-2407
             Project: OpenJPA
          Issue Type: Bug
          Components: Enhance
    Affects Versions: 2.2.2
         Environment: Windows 8 using MySql Cluster
            Reporter: Serdyn du Toit


Hi,

I'm seeing some problems when my persistence.xml is populated with details for MySql Cluster
- but when I work against HSqlDb everything is working great.




First issue during build-time enhancement:
I get the following even though I don't have any @Embeddables in my code
[openjpac] 407  testdb  ERROR  [main] openjpa.Enhance - The identity field defined in the
code.shared.DataBean Embeddable is not supported. 
 
Someone else has also encountered this issue: http://stackoverflow.com/questions/16619860/openjpa-enhance-the-identity-field-defined-in-the-0-embeddable-is-not-suppo



Second issue at runtime:
During the second invocation of a method that should return everything from a table I get
the following stacktrace:
1797  testdb  TRACE  [main] openjpa.jdbc.JDBC - <t 488448102, conn 0> [1 ms] close
<openjpa-2.2.2-r422266:1468616 nonfatal general error> org.apache.openjpa.persistence.PersistenceException:
