thanks for the comment.
Indeed, the method cited below has been introduced with JDBC 4.1 (Java 7).
I opened a bug  to add Java 7 compliance.
I also submitted a patch that is already available in the master branch and the update site .
However, some JDBC drivers not yet support JDBC 4.1 (Java 7), for example the MySQL connectors .

Subject: [gemini-dev] Gemini DBAccess - JDBC 4.1 getParentLogger
I found the new release of Gemini DBAccess and be really happy
to see MySQL shipped :)
However there's a compilation error on all DataSource because
this method is not implemented:
public Logger getParentLogger() throws SQLFeatureNotSupportedException
This seems to be a new method in CommonDataSource interface.
I'm using Eclipse 4.2M6 with javax.persistence version 2.0.4. When will
this be updated?
