### Question
- What do you want to know?
When I sent the request, I saw the NullPointerException in the skywalking-api.log file. Does Skywalking 8.0.1 support vertx 3.8.5 ? How should I solve this problem？
- Which version of SkyWalking, OS and JRE?
SkyWalking 8.0.1
vertx 3.8.5
k3s v1.18.4 + k3s1

1. I installed Skywalking through the Rancher store
2.I copy /agent directory to the project source directory， only changed the agent.service_name, Collector.backend_service, in the Skywalking configuration file
3.Package images with Docker，Start with java -javaagent:/agent/skywalking-agent.jar -jar
4.Access any route
5.I find errors in the default /agent/logs/skywalking-api.log

@T-baby, how did you determine that there are no tests for Vert.x 3.8+? There are basic tests for 3.0.x - 3.9.x.
What additionally should be tested and can you produce this issue in a demo repo?

@LinXiaoJian, unfortunately, those images aren't enough for me to help. Most of that code seems to be more custom than Vert.x idiomatic. Are you able to produce this issue in a project you can send me the source code for (via GitHub)? Preferrable the minimally reproducible one.
I don't think Kotlin should cause the issue you're seeing.

@LinXiaoJian, I can help you with the Vert.x issue if you provide some sample code or more information about the issue but I'm not sure what mysql-connector-java has to do with Vert.x. They are unrelated and should not affect each other.
