Ubuntu – JVM problem while running eclipse

I have installed Java 9 JDK on my Ubuntu. Now I need to install Eclipse. I have downloaded and extracted Eclipse Mars to /opt folder. When I started eclipse from console I got error:

gedas@gedas-Latitude-E5450:/opt$ cd eclipse
g@g-Latitude-E5450:/opt/eclipse$ ./eclipse 
Unrecognized VM option 'MaxPermSize=256m'
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
g@g-Latitude-E5450:/opt/eclipse$ 

And message box:

java -version returns
