RemoteDependency ResultCode always set to 0 under Spring Boot 4

[petergphillips]

Expected behavior

The ResultCode is populated with the correct value from the remote dependency call.

Actual behavior

The ResultCode is always 0. Note that Success is true. It used to be set before we upgraded to Spring Boot 4.

To Reproduce

This issue only started happening after the upgrade to Spring Boot 4.

Please see microsoft/ApplicationInsights-Java-Repros#18 for an example and instructions to reproduce.

With console debug on I can see

{"ver":1,"name":"RemoteDependency","time":"2026-02-13T15:01:15.496Z",...,"resultCode":"0","data":"http://localhost:8080/rest-greeting","type":"Http","target":"localhost:8080","success":true,"properties":{"_MS.ProcessedByMetricExtractors":"True"}}}}

appearing in the logs.

Just tried again with Agent 3.7.8.
The call to /web-greeting is now working, but the call to /rest-greeting still has a result code of 0. Note that the call to /rest-greeting uses org.springframework.web.client.RestClient as opposed to org.springframework.web.reactive.function.client.WebClient.
