Clipsal cbus Cgate openhab binding

Hi
I was trying to setup cbus openhab on my Rpi 3 model B.My pi has jessie lite running.
I have followed all the steps.The issue I am facing is that whenever I install eclipse
My cgate server stops responding.It does not start.I think it is due to open jdk 7 jre package in eclipse.C - Gate 2.11.1 runs only on java 8. Due different version of java it does not start.
Any solutions to this issue.
