> JPA 2.0 has introduced a specification for strictly-typed dynamic query
> construction. The type-strictness is based on availability of a meta-model.
> The user application can either use meta-model API to access the type
> information or instantiate the meta-model (referred as canonical meta-model)
> with a set of auto-generated classes for compile-time binding. This issue
> refers to instantiating the canonical meta-model at compile-time.
> The process involves processing source code annotations or xml descriptors.
> Annotation processing support in Java platform has significantly changed
> across JDK version 5 and 6. In JDK5, the annotation processing was supported
> by a command-line tool named apt based on com.sun.mirror API library. In JDK
> 6, the annotation processing is more seamlessly integrated with javac
> compilation process with javax.annotation API libraries.
> It is not obvious at this point on how to hook into compiler life-cycle when
> source code has *no* annotation and persistence meta-data is *only* available
> in XML descriptors.
