Use

<property name="" value="mysql" />

in the persistence.xml of yours to avoid the info message. You may use
it to further fine-tune the jpa provider and its underlaying resources
like database connections.

I haven't tried it out myself, though so use it on your own risk ;-)

Could you show the PositionLog entity and the corresponding
persistence.xml file with other referenced files (like orm.xml and
other mapping files if such exist)?
