769 db WARN [main] openjpa.Enhance - Creating subclass for "[class
openjpatest.Group, class openjpatest.Organization, class
openjpatest.AddressBook]". This means that your application will be less
efficient and will consume more memory than it would if you ran the OpenJPA
enhancer. Additionally, lazy loading will not be available for one-to-one and
many-to-one persistent attributes in types using field access; they will be
loaded eagerly instead.

> Splitting out this item from OPENJPA-1804.
> The dynamic loading of the enhancer agent on Mac OS X w/ Java 1.6.0 fails due
> to the packaging differences on the Mac, where instead of a tools.jar, there
> is a 1.6.0/Classes/classes.jar that we should be using instead.
