In debug I see following row:
It is usuall apache http client.
But in fiddler I don't see this request.
I gave read following article Configure a Java Application to Use Fiddler
And jvisualvm shows following information:
In fiddler I see all requests from browser.
How to see request from backend?
UPDATE
while this row executes I see java.net.ConnectException: Connection refused: connect
but I think that i anyway should to see attempt to make request
