---------------------------------------

Before fix -
768  db  TRACE  [main] openjpa.Enhance - org.apache.openjpa.enhance.InstrumentationFactorygetInstrumentation() _disabled: _inst:null_dynamicallyInstall:true
768  db  TRACE  [main] openjpa.Enhance - org.apache.openjpa.enhance.InstrumentationFactory.findToolsJar() -- couldn't find /System/Library/Frameworks/JavaVM.framework/Versions/1.6.0/Home/lib/tools.jar
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.


After fix -

> 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.
