( this is a maven2 project, and you can reproduce the bug by starting derby on localhost
and doing a "mvn install". the resulting error message during enhancement is:
>     [java] Exception in thread "main" <4|true|0.9.6-incubating> org.apache.openjpa.util.MetaDataException:
The id class specified by type "class" does not match the primary
key fields of the class.  Make sure your identity class has the same primary keys as your
persistent type, that the access types are the same, and if you are getting this error at
runtime, that you have your persistent class since last compiling your identity class.
