Looks like there's two routes for doing build-time enhancement/instrumentation.

My rationale for making the patch was as part of an upgrade from Hibernate 3.x, I was using the Ant InstrumentTask in my build to get field accessors. Upgrading to 4.x, I found the ant task was still there, so I assumed it was still "the way" to doing build-time instrumentation.

Is the InstrumentTask now deprecated then in favour of the EnhancementTask/Mojo, or do they serve different use-cases?
