   Hi, I'm currently working with the pulsar-functions-local-runner 2.7.1 dependency and a JDK 8, and I get this same error when I run my application.
   
   It throws when I instantiate the FunctionConfig class like the [example](https://pulsar.apache.org/docs/en/functions-debug/#debug-with-localrun-mode) in the doc.
   
   Error:
   
   ```java
   Exception in thread "main" java.lang.SecurityException: Invalid signature file digest for Manifest main attributes

   ```
   
   @jiazhai, did the #8491 solve this problem for pulsar-functions-local-runner ?
   
   Thanks.
