Context

In https://github.com/eclipse-vertx/vert.x/actions/runs/20499367576/job/58904378867 the test failed, and it is an unstable test.

When analyzing the test, I found the following:

• Http2ClientConnectionImpl.onStreamClosed() calls super.onStreamClosed(s) which will return the connection to the pool
• When doing that, the expirationTimestamp is not set yet, and due to that the isValid() will return false and evict the SharedHttpClientConnectionGroup.checkExpired() will have a short time window to close the connection before the Http2ClientConnectionImpl.onStreamClosed() set the expirationTimestamp and make the connection valid again.

Steps to reproduce

I was able to reproduce it locally with several breakpoints and some delays in the test.

I'll prepare a pull request.

Do you have a reproducer?
