Could this also explain the log warning you were seeing?

If the new operator was called before Spring was initialized, the =20
aspect would try to inject the new object, but fail because Spring =20
won't yet have configured the aspect itself.

The reason it is a warning rather than an error is that this allows =20
for independent testing of the domain objects without Spring around.

That doesn't totally surprise me. There is a *lot* more work going on =20=

when you load-time weave than when you simply load an existing class. =20=

The whole aspect weaver has to be fired up, byte codes loaded into =20
memory and examined, then possibly transformed before being defined. =20
We're continually working on ways to reduce LTW footprint and weave =20
times (AspectJ 1.5.1 is better than 1.5.0 in this regard, and we have =20=

more to do in 1.5.2), but LTW will always be more expensive than =20
straight class loading.
