Me and my team mates are facing same kind of problem with Jdeveloper Integrated Web Logic server.
Its not coming up at all.
We tried below steps :
1. uninstalling and installing Jdeveloper couple of time.
2. Removed Default Domain folder and let it get created again while running Server through (Jdeveloper Run Start Server Instance).
3. restarted machines couple of time.
It used to work couple of months back and suddenly it stopped for all of us.
Our team is using Jdveloper version:- 12.2.1.2 and 12.2.1.3
Thanks
