In my application, I’m using the following pointcut expression to intercept all methods in classes annotated with my custom annotation.

@Pointcut("@target(io.github.jamestrandung.memoize.Memoized) && execution(* *(..))")
public void methodInMemoizedType() {
}

When I start my SpringBoot app, I keep getting the error below.

Caused by: java.lang.IllegalArgumentException: Cannot subclass final class org.springframework.boot.autoconfigure.AutoConfigurationPackages$BasePackages

I tried to shorten my pointcut expression to execution(* *(..) and got exactly the same error and I can understand why. However, this means the 1st part of my expression @target(io.github.jamestrandung.memoize.Memoized) has no effects at all.

I’d be very grateful if you could tell me what I did wrong.
