Yes, the port is up and waiting for connections, ie. the app/demon behind it. Connections usually are seen with client IP addresses where the *.* is and also with something like "ESTABLISHED" as status.
If you see a name at the positon where the 8090 is, this is translated from the /etc/services, where port numbers can be mapped to a service name.
Next time please checkout a more appropriate subforum since this is "Shell Programming and Scripting"
