      I have been observing this for a while now. Once in a while, this test hangs.

      The non-deterministic failure has become deterministic in this PR: [UNDERTOW-2568UNDERTOW-2569 Backport fixes and enhancements to 2.2.x by fl4via · Pull Request #1763 · undertow-io/undertow|https://github.com/undertow-io/undertow/pull/1763]. It hangs indefinitely only on Windows when using the JDK 11.0.27.tem.

      I am assuming both the eventual hang and this one to be caused by the same issue.

      When reproducing this on a local Windows machine, I was able to view the stack trace of the test:
