[Bug] ClassNotFoundException error occurred when using Function development in the kubernetes cluster

### Search before asking

- [X] I searched in the [issues](https://github.com/apache/pulsar/issues) and found nothing similar.

### Read release policy

- [X] I understand that unsupported versions don't get bug fixes. I will attempt to reproduce the issue on a supported version of Pulsar client and Pulsar broker.

### Version

- kubernetes: 1.28
- jdk: 17
- pulsar: 3.2.1
- pulsar-functions-pulsarctl-java-runner: 3.2.1.2

### Minimal reproduce step

1. Develop using the Extended Pulsar Functions SDK for Java and connect to the Redis cluster
2. Edit yaml file
3. kubectl apply -f function.yaml

### What did you expect to see?

The function can connect to the Redis cluster and work properly.

### What did you see instead?

### Are you willing to submit a PR?

- [ ] I'm willing to submit a PR!

Start with the supplied Function YAML and trace the reported failure through PulsarSink.java, Reflections.java, and JavaInstanceRunnable.java. Reproduce the Java function deployment with the stated runner and output type, then determine what prevents com.alibaba.fastjson2.JSONObject from loading. Done means the function starts and connects to Redis without the ClassNotFoundException.
