MicrometerHttpRequestExecutor bad tag values in 1.13.6 / httpclient 5.4 async

[flozano]

After upgrading to 1.13.6 / HttpClient 5.4, with the fix of #5575, I get again the request metrics, but something has changed.

In the classic Http Client case, it works exactly as before.

In the async Http Client case, before Http client 5.4 I got:

httpcomponents_httpclient_request_seconds_sum{httpclient="hc5async",method="GET",outcome="CLIENT_ERROR",status="401",target_host="0.0.0.0",target_port="50964",target_scheme="http",uri="/"}

now I am getting:

httpcomponents_httpclient_request_seconds_sum{httpclient="hc5async",method="GET",outcome="CLIENT_ERROR",status="401",target_host="UNKNOWN",target_port="UNKNOWN",target_scheme="UNKNOWN",uri="/"}

is this expected?

please ignore. async does not use this method obviously 🤦
