Update to Vert.x 5? #18
Description
Currently there is no public metadata for Netty 4.2.
Until it is contributed, the best option is to run the application with the GraalVM agent to dump metadata before create the native image.
This is more or less what is explained in https://graalvm.github.io/native-build-tools/latest/maven-plugin-quickstart.html
And I'm not sure there is much value in reproducing this how-to with Vert.x (because there's nothing specific to Vert.x)
For the record, I tried building a native-image with the help of the agent, and it worked.
