Thanks for the help!
I actually got it working by changing my binding file. Here is my use case:
public interface Engine{
void setName(String name);
String getName();
}
public class EngineImpl implements Engine{
// Implement methods above
}
public class StyleImpl implements Style{
// Didn't show Style interface for brevity
private Engine engine;
}
I was getting an error using this mapping on the Style binding:
<structure name="engine" field="engine" usage="optional" />
However I changed it to use the 'map-as' attribute and it worked
correctly and stopped trying to instrument the Engine interface.
<structure field="engine" usage="optional"
map-as="com.edmunds.vehicle.jpa.EngineImpl"/>
I wasn't ever trying to reference the actual Engine interface in my
binding file however since the interface was being used in the
StyleImpl class and the binding wasn't specifying a class to use it
was trying to instrument the Engine class.
Thanks again!

Don't miss this year's exciting event. There's still time to save $100.
Use priority code J8TL2D2.
