Serdyn du Toit updated OPENJPA-2407:
------------------------------------

    Attachment: sandbox-mysqlc16.zip

sandbox-mysqlc16.zip

Fixed.  This is however a MySql Cluster (NdbOpenJPAStoreManager OpenJpa extension not maintained
in OpenJpa) issue and will be raised with them.

Leaving this open until its resolved and anyone want to use this channel to communicate about
it (close if you want)

> 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:
