Hotkeys don't work, but those with modifiers do.

[mmyfl]

What steps will reproduce the problem?

Open a layer, draw, drag as usual, press some hotkeys.

What is the expected result?

Activate corresponded functions.

What happens instead?

Hotkeys with modifiers (e.g. Shift-M) function as expected, but single key hotkeys (e.g. a, m, p etc) just don't work (but debug output do show something).

Please provide any additional information below. Attach a screenshot if possible.

I've tried a very old version (3376), still the same. I'm using Debian 8/MATE 1.8/OpenJDK 7.

Your debug_info is very helpful. It appears, that JOSM does register the events. But the test AdvancedKeyPressDetector.isFocusInMainWindow​ fails for some reason.

I have found the reason (and even more bugs!). After I switched off input method, everything is ok. It looks like JOSM hates CJK environment.

What kind of input method are you using? The only issue I'm aware of, is that the keyboard sometimes stops working with ibus (#11209).

Exactly ibus. With IM, I've encountered this problem, that problem(#11209), eating IM buffer too eagerly, and even severe bug.
