Steps to reproduce:

Open a Java app that contains a progress bar (for example I tested with this gist https://gist.github.com/brunosantanati/3c9e5778ba591b6218b6a210da1fc17f or Intellij).

Actual behavior:

NVDA does not beep or speak the percentage when it finds a Java progress bar.

Expected behavior:

NVDA should beep or speak on the progress bar, depending on the progress bar setting set.

Other questions

Does the issue still occur after restarting your computer?

Yes.

Have you tried any other versions of NVDA? If so, please report their behaviors.

I tried both 2021.3.3 and source-master-c446688, it still occurs.

If NVDA add-ons are disabled, is your problem still occurring?

Yes.

Does the issue still occur after you run the COM Registration Fixing Tool in NVDA's tools menu?

Since it was a bug on the access bridge handling code, I did not run it, but I imagine it does.
