Recently we upgraded from Wildfly 26.1.2 / Mojarra 2.3.14.SP04 to WildFly Full 28.0.1 / Mojarra 4.0.0.SP01.
Since then, when using Firefox, we've been getting a lot of warnings for random resource files in the log like:

I found this similar post in the PrimeFaces forum that tracks this to a Firefox feature called race cache with network (RCWN). And sure enough, when turning off RCWN, we no longer see any exceptions. But of course we can't turn the feature off for all our clients.
The best way I found to reproduce the issue is to turn on the Firefox setting Startup / Open previous windows and tabs, visit a page that loads some of resource files, close Firefox and open it again so that it right away loads the same page. But it also happens when just navigating in our application without restarting Firefox.
I'm not totally sure that Mojarra is the right place to have a look at this, but since the PF forum links to a similar fix in MyFaces, maybe you can help us in this case as well.
