Class Loader still used while it's supposed to be closed#41233

As part of my work trying to improve the CL situation, I stumbled upon a few cases of $TITLE for which I would need some help.

In my patch, I introduce a safe guard throwing an exception when you are trying to load a class from a CL that has been previously closed.
The rationale is that we shouldn't load any class from a CL that has been closed.

I already fixed a few of these problems... but I still have some going on that are a lot less easy to pinpoint.

These issues where all observed in this specific CI job run: https://github.com/gsmet/quarkus/actions/runs/9535653448/job/26281846636

  1. io.vertx.core.impl.VertxImpl$1.operationComplete

This one is due to the delay to handle the graceful shutdown:

From io.vertx.core.impl.VertxImpl:

       eventLoopGroup.shutdownGracefully(0, 10, TimeUnit.SECONDS).addListener(new GenericFutureListener() {
            @Override
            public void operationComplete(io.netty.util.concurrent.Future future) throws Exception {
              if (!future.isSuccess()) {
                log.warn("Failure in shutting down event loop group", future.cause());
              }
              if (metrics != null) {
                metrics.close();
              }
              if (tracer != null) {
                tracer.close();
              }

              checker.close();

              if (completionHandler != null) {
                eventLoopThreadFactory.newThread(() -> {
                  completionHandler.handle(Future.succeededFuture());
                }).start();
              }
            }
          });

                }
                boolean continueOnFailure = classTransformers.stream()

  1. Issues in DevUIGrpcSmokeTest

Hard to figure out what's going wrong here as we don't have the stacktraces handy.
