I have been using SO chat facility since last couple of months. Multiple time I have observed that, suppose I am in one chatroom and I get notification as shown above. When I go to that room I find that that notification was not for me but for some one else.!! This happens because, if two users have similar name (like in my case it was java_developer - mine and java - another user) then I get this notification even though I am not the intended person. (By pointing like @java, we both are probably referenced.)
I hope I am clear with my question. Please take note of this possible issue.
