1.17pre2 to 1.17 upgrade results in a low-cpu server hang post world load

While I realize this may not be a supported scenario it's possible the hang would repro outside of this scenario so I figured it might be worth reporting.  I can provide core dumps (I can probably also get jmap to run if needed) and/or the world save for repro.  I could also provide strace/similar output.

Last output is along these lines:

[05:18:26] [Server thread/INFO]: Starting GS4 status listener
[05:18:26] [Server thread/INFO]: Thread Query Listener started
[05:18:26] Query Listener #1/INFO: Query running on 0.0.0.0:25566

The server fails to allow connections and also fails to respond to "stop" or other console commands after it hangs - there is a short period post-startup where you can connect and/or run console commands prior to the hang.
