Weird bug in the community edition plugin when editing any java code

[Ulimn]

I am using IntelliJ Community Edition and the Quarkus Tools plugin.

Whenever I make any change in my code, in the status bar there is some kind of event/message saying "Computing Java diagnostics". When I type the code at regular speed, it is noticable, there are mini-hangs after each keystroke.

Quarkus Tools and the necessary Red Hat Telemetry plugins are the only ones enabled. I'm on MacOS on an M1 MacBook Air machine, latest Big Sur - if it matters.

I attached a small video showing the problem: https://user-images.githubusercontent.com/1268347/134785961-c50400c5-f455-43ec-8f96-ef14eaa94e5a.mov

What might be the issue here? Can I provide any more details?
