Description

The PCEnhancer blows up if you have a non-OpenJPA persistence provider defined and available on the classpath. This makes comparisons between providers more than a little unfriendly.

Example stack :

204 OpenJPAPU INFO [main] openjpa.Tool - No targets were given. Running on all classes in your persistent classes list, or all metadata files in classpath directories if you have not listed your persistent classes. Use -help to display tool usage information.
