Issue with starting OWT server

[Arjun]

I installed OWT server from this https://github.com/open-webrtc-toolkit/owt-server/blob/master/doc/servermd/Server.md . When I tried to start the server, I am getting error in starting the management-console. I checked the managment-api.stdout file. Here is the error which I am getting
