When load time weaving is enabled spring loads classes into a temporary class loader to do type matching (is this a factory bean? etc.). As this type matching class loader is recreated for each type matching attempt there can be a lot of them. For each class loader we run a bunch of matchers that call
getResource. With these temp class loaders this can consume excessive amount of time. As we don't really need to instrument the classes in temp class loaders we can just exclude it.
