Unstable test HttpBandwidthLimitingTest.testDynamicOutboundRateUpdateSharedServers [4.x]

[ahus1]

Version

4.x

Context

In the 4.x branch, the test HttpBandwidthLimitingTest.testDynamicOutboundRateUpdateSharedServers is unstable:

https://github.com/eclipse-vertx/vert.x/actions/runs/20537844506/job/58998382133?pr=5859

Steps to reproduce

When calling updateTrafficShapingOptions() while the code for listening is still running, some instance variables might not have been initialized yet by the synchronized block.

In the master branch, the code of the test has been refactored to (1) call the traffic shaping only after all server have been initialized and (2) only once per server.

I'll suggest a PR to stabilize this later today here: #5864.

Do you have a reproducer?

Closing as it was unstable only in the 4.x branch.
