Hello. I tested the memory issue and realized that you actually should increase `-Xms` argument value if you want to increase maximum amount of memory used. It also could be that the line where you put your argument isn't somehow working.
The "java" process shown with 1G is actually the process for elasticsearch so you shouldn't worry much about it. Here is some sample configuration that uses more memory. ![alt text][1]

You can also enable heap status like on the screenshot by going to preferences ->General and Show heap status
