ExceptionInInitializerError when initializing VertxByteBufAllocator

Version

5.0.0.CR1

Context

In an app started in kubernetes with 0.1 vCPU and 1 Gib memory, I get an ExceptionInInitializerError that I don't get on my local machine.

Do you have a reproducer?

Not yet. I'm trying to reproduce locally with docker

Steps to reproduce

Native transport is preferred using netty-transport-native-io_uring

The code to trigger this is simply:

val vertx = Vertx.vertx(vertxOptionsOf(preferNativeTransport = true))
vertx.fileSystem().readFileBlocking(path.toString())

Extra

Tested with java 23 on linux
