Unrecognized VM option 'MaxPermSize=350m'
pycharm 64 bit not work with 

java 8

above ...... 

maximum size allowed 350
Use Java 7 instead.
Pycharm 5 

Problem : Unrecognized VM option 'MaxPermSize=350m'

Java version

java version "1.9.0-ea" Java(TM) SE Runtime Environment (build
  1.9.0-ea-b91) Java HotSpot(TM) 64-Bit Server VM (build 1.9.0-ea-b91, mixed mode)

I have commented the line by watching the Google solution in 

pycharm64.vmoptions

file. But unfortunately Pycharm is not opening. What is the idea to gear it up ?
