     * Given a method, which may come from an interface, and a target class used in the current reflective invocation, find the corresponding target method if there is one. E.g. the method may be <code>IFoo.bar()</code> and the target class may be <code>DefaultFoo</code>. In this case, the method may be <code>DefaultFoo.bar()</code>. This enables attributes on that method to be found.

     * <b>NOTE:</b> In contrast to {@link org.springframework.aop.support.AopUtils#getMostSpecificMethod}, this method does <i>not</i> resolve Java 5 bridge methods automatically. Call {@link org.springframework.core.BridgeMethodResolver#findBridgedMethod} if bridge method resolution is desirable (e.g. for obtaining metadata from the original method definition).

     *          the method to be invoked, which may come from an interface
     * @param targetClass
     *          the target class for the current invocation. May be <code>null</code> or may not even implement the method.
     * @return the specific target method, or the original method if the <code>targetClass</code> doesn't implement it or is <code>null</code>
