> The message are
> 250  test  TRACE  [main] openjpa.MetaData - Finished parsing metadata resource "file:/C:/workspace/jpatest/TestOpenJPA/bin/ptp/test/issue5/orm.xml".
> 250  test  TRACE  [main] openjpa.MetaData - Parsing class "ptp.test.issue5.T5Entity".
> 250  test  TRACE  [main] openjpa.Enhance - Enhancing type "class ptp.test.issue5.T5Entity".
> 250  test  WARN   [main] openjpa.Enhance - Type "class ptp.test.issue5.T5Entity" has no metadata; enhancing as persistence aware. If you intended for "class ptp.test.issue5.T5Entity" to be persistence-capable, then this means that OpenJPA could not find any metadata for "class ptp.test.issue5.T5Entity". This can happen if the directory containing your metadata is not in your CLASSPATH, or if your metadata files are not named properly. See the documentation on metadata placement for more information.
> 250  test  TRACE  [main] openjpa.Tool - The class does not have metadata - enhanced as persistence-aware.
