Hi Stephen - we are checking this. Thanks for reporting.
Sorry for the upgrade issue.
No problem! I can work around it. No biggie. I'm glad I could help if only a little bit.
I've created the following JIRA to track this out https://issues.jboss.org/browse/PLINK-371. It was probably a mistake.
Btw, the simple schema is only a mapping example using the JPA annotations. You can always use them to create your own entity model to better fit your requirements, using the simple schema as an example or not.
Thanks for the heads up.
