--- Comment #14 from Rainer Jung <rainer.j...@kippdata.de> ---
Finally for the sake of completeness the stacks of the two loading calls for
the class to get woven.
First call (happening before Spring called addTransformer()). Here
name="de/kippdata/demo/weave/Greeting.class",
path="/de/kippdata/demo/weave/Greeting.class", so the class was loaded as a
resource:

Second call, now with transformers in place but with class already cached. Here
name="de.kippdata.demo.weave.Greeting",
path="/de/kippdata/demo/weave/Greeting.class", so the class was loaded as an
actual class:

Before 7.0.70, the two calls did not use the same path for resource and class,
so they did not share the cache entry. After the optimization in r1745608 they
do.
