One JDWP test failed when using a `*.local` address for JDWP:

` -Xrunjdwp:transport=dt_socket,address=Mac-1762967583261.local:49212` 

With:


2025-11-12T17:27:03.7710510Z ERROR: transport error 202: getaddrinfo: unknown host
2025-11-12T17:27:03.7742510Z ERROR: JDWP Transport dt_socket failed to initialize, TRANSPORT_INIT(510)
2025-11-12T17:27:03.7762640Z JDWP exit error AGENT_ERROR_TRANSPORT_INIT(197): No transports initialized [src/jdk.jdwp.agent/share/native/libjdwp/debugInit.c:745]


This is nothing new. `macos-13` GHA runners were also unable to resolve `*.local` addresses using `getaddrinfo` (see [this issue](https://github.com/actions/runner-images/issues/8649), [or this reproducer](https://github.com/vieiro/gha-macos-resolve-hostname) ) and the problem may be also happening in `macos-15-intel` GHA runners. I'll try to reproduce and file a new issue.
