@Override
public boolean matches(Method method, Class<?> targetClass, boolean beanHasIntroductions) {

    Method targetMethod = AopUtils.getMostSpecificMethod(method, targetClass);
    ShadowMatch shadowMatch = getShadowMatch(targetMethod, method);

    // Special handling for this, target, @this, @target, @annotation
    // in Spring - we can optimize since we know we have exactly this class,
    // and there will never be matching subclass at runtime.

        // A match test returned maybe - if there are any subtype sensitive variables
        // involved in the test (this, target, at_this, at_target, at_annotation) then
        // we say this is not a match as in Spring there will never be a different
        // runtime subtype.
        RuntimeTestWalker walker = getRuntimeTestWalker(shadowMatch);
        return (!walker.testsSubtypeSensitiveVars() || walker.testTargetInstanceOfResidue(targetClass));
