[Tracing Agent][GR-64510] Collect Metadata with the Tracing Agent

[alixiaodi]

Describe the Issue

I am currently using any plugin to package Maven projects into JAR files. My project is a JavaFX project with CSS and FXML. When executing - agentlib: native image agent, it will start my project, but clicking on the above operation will result in an error and the final generated native image is incomplete.

Using the latest version of GraalVM can resolve many issues.

• I tried with the latest version of GraalVM.
