DESCRIBE THE ISSUE IN DETAIL: The emulator CLI's -dns-server option does not seem to work on API 31 or newer.

STEPS TO REPRODUCE:

Run a local dns server and log queries: dnsmasq -dq
Start an API 31 emulator: emulator -avd emulator31 -dns-server 127.0.0.1
Resolve a domain: adb shell ping www.reddit.com
dnsmasq does not show that domain in the log.

However, on API 30, these same steps will result in the dnsmasq showing the queries to reddit.com:

dnsmasq: query[A] www.reddit.com from 127.0.0.1
dnsmasq: forwarded www.reddit.com to <ip>
dnsmasq: reply www.reddit.com is <CNAME>
dnsmasq: reply reddit.map.fastly.net is <ip>

We need to override some DNS entries in order to test our app in environments that do not have external internet access, but it stopped working in API 31 or newer.

Adding 2 more thread dumps from another freeze. Again after switching branches and updating from git.

Thanks for the report. I believe that this is fixed in our development branch, and also in the branch that will become Ladybug Feature Drop Beta. If you could verify that this doesn't happen in a nightly build (from https://developer.android.com/studio/nightly) that would be helpful -- and of course if you can trigger this in a recent nightly build, that's would be very important information.

Sorry, I have not tried it on the nightly build, but since then I updated to Meerkat and I have not seen the freeze afterwards.

Marked as fixed.

That's good to hear. I think that the fix (which for reference was https://github.com/JetBrains/intellij-community/commit/fe621544dd61a9af34d97958d3d823a7c3454a87) is effective for both beta and canary branches.

For the record I am also arranging for https://github.com/JetBrains/intellij-community/commit/a444c8a500883669fc05c7177f93b5b794fdd13b (same fix, different implementation class) to be included; it's probably inactive code in our configurations, but it might be possible to trigger nevertheless.

Thanks for the confirmation!
