Happy New Year, and happy new decade of system time. I'm using NetBeans 11.1 under macOS Catalina 10.15.2 (I think I was still on Mojave when I first installed NetBeans 11.1).
Since last year I've been noticing that sometimes when I start NetBeans, the Javadoc window is missing. I like to keep it grouped with Output and Test Results. And then the last project I was working on is no longer recognized as valid NetBeans project, but it still opens, so I have to close all projects to close it and quit and restart NetBeans. And then I can bring back the Javadoc window and have it function as expected. Maybe these two things are related, and so far it seems that as long as I take care that Output or Test Results, and not Javadoc, is frontmost when I quit NetBeans, I won't have this problem the next time I start NetBeans. This is a minor nuisance, maybe it's been resolved in NetBeans 11.2 or later. But this by itself wouldn't be enough for me to upgrade.
