excuse me:
String SCOPED_TARGET_NAME_PREFIX = "scopedTarget."; under what circumstances will this prefix be used?

public abstract class AbstractHandlerMethodMapping<T> extends AbstractHandlerMapping implements InitializingBean {

    /**
     * Bean name prefix for target beans behind scoped proxies. Used to exclude those
     * targets from handler method detection, in favor of the corresponding proxies.
     * 
We"re not checking the autowire-candidate status here, which is how the
     * proxy target filtering problem is being handled at the autowiring level,
     * since autowire-candidate may have been turned to {@code false} for other
     * reasons, while still expecting the bean to be eligible for handler methods.
     * 
Originally defined in {@link org.springframework.aop.scope.ScopedProxyUtils}
     * but duplicated here to avoid a hard dependency on the spring-aop module.
