We're going to need to adjust the code before we can merge this:

Warning: /home/runner/work/gson/gson/gson/src/main/java/com/google/gson/internal/bind/TypeAdapters.java:[573,35] [AddressSelection] Prefer InetAddress.getAllName to APIs that convert a hostname to a single IP address
(see https://errorprone.info/bugpattern/AddressSelection)
...
Error: warnings found and -Werror specified

For this code:

      // regrettably, this should have included both the host name and the host address
      return InetAddress.getByName(in.nextString());

I think we should probably just add @SuppressWarnings("AddressSelection") to the containing method, or introduce a local variable so we can narrow the scope of the suppression.

Looks like com.google.errorprone:error_prone_core is up-to-date now, so this is no longer needed.
