[ci-scan] Test failure: ShutdownTests.ShutdownTestRun on crossgen2 (No process associated)

[github-actions]

Build Information

Build: https://dev.azure.com/dnceng-public/public/_build/results?buildId=1484682
Build error leg or test failing: linux-x64 Release TestReadyToRun_Libraries - Microsoft.Extensions.Hosting.Functional.Tests

Error Details

ShutdownTests.ShutdownTestRun fails on the linux-x64 Release TestReadyToRun_Libraries leg of runtime-coreclr crossgen2 (def 124) with System.InvalidOperationException : No process is associated with this object.. The exception is thrown from Process.get_HasExited() called by DeploymentResult.AssertStillRunning().

[FAIL] Microsoft.AspNetCore.Hosting.FunctionalTests.ShutdownTests.ShutdownTestRun
      System.InvalidOperationException : No process is associated with this object.
         at System.Diagnostics.Process.get_HasExited()
         at Microsoft.AspNetCore.Server.IntegrationTesting.DeploymentResult.AssertStillRunning()
         at Microsoft.AspNetCore.Hosting.FunctionalTests.ShutdownTests.ShutdownTestRun(String identifier, String shutDownMechanism)

This is distinct from the NativeAOT variant (#129961) which fails with PlatformNotSupportedException (Assembly.GetCallingAssembly not supported). The crossgen2 variant reaches process launch but the process exits before HasExited can be checked.
