      Description

      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: null
