/**
* Tests for AspectJ pointcut expression matching when working with bridge methods.
*
* <p>Depending on the caller's static type either the bridge method or the user-implemented method
* gets called as the way into the proxy. Therefore, we need tests for calling a bean with
* static type set to type with generic method and to type with specific non-generic implementation.
*
* <p>This class focuses on JDK proxy, while a subclass, GenericBridgeMethodMatchingClassProxyTests,
* focuses on class proxying.
*
* See SPR-3556 for more details.
