I'm starting slow with a couple of domain classes, each with a couple of
basic attributes, and each with a single OneToMany collection, one
referencing the other, and the second referencing the same entity.
I'm trying to have a mix of annotations and XML metadata, by only using
"logical" annotations, and the XML specifies what would have been done
with the physical annotations.
When I run the enhancer task, I get a NoSuchFieldException on the first
"basic" element. The "name" value is the property name in the class.
Included here are the relevant excerpts of my entity classes,
persistence.xml, and orm.xml file. I removed the getters/setters from
the classes and the package/imports. I replaced a couple of unimportant
strings in the persistence.xml and orm.xml with "<<...>>>" wrappers.
At the end I have my build output, showing the NoSuchFieldException.
I've marked line 14 in the orm.xml file.
Is there anything obviously wrong here?
