Used VM option to config vert.x deployment option, But setter invoke method is Unreachable.

Questions
I used -Dvertx.deployment.options.threadingModel=VIRTUAL_THREAD to config vert.x deployment option, when i debug it, I found some code is Unreachable.

Version
4.5.9

Context
In io.vertx.core.impl.launcher.commands.BareCommand#configureFromSystemProperties method ,when the param 'prefix' value is 'vertx.deployment.options.', but log is null, thats why vertx options setter invoke not execute. after this, I found in io.vertx.core.impl.launcher.commands.BareCommand#startVertx method line 226, the code 'configureFromSystemProperties.set(null);' make log is null.

the chain is :
io.vertx.core.impl.launcher.VertxCommandLauncher#execute
io.vertx.core.impl.launcher.commands.RunCommand#run
io.vertx.core.impl.launcher.commands.BareCommand#run(java.lang.Runnable)
io.vertx.core.impl.launcher.commands.BareCommand#startVertx
and in BareCommand line 226 code 'configureFromSystemProperties.set(null);'

Do you have a reproducer?
This is easy to reproducer

Steps to reproduce
config -Dvertx.deployment.options.threadingModel=VIRTUAL_THREAD VM option
use launcher to deploy, like new Launcher().dispatch(args)
debug
reproduce

OS: Apple M1 Pro ventura 13.6
JDK: java version "21.0.4" 2024-07-16 LTS

finally, I used beforeDeployingVerticle() method in Launcher class to resolve my problem by hook deployment options, but Im still think this is a bug...

if i do it in wrong way, reply and close this issue plz.
