To fix this problem is easy, you can search much solutions by google, today i introduce my solution steps.
Step 1: Close your eclipse and edit eclipse.ini
If you have opened window of eclipse, you should close it.
Then you should open eclipse.ini file and edit it.
If you do not know where this file is, you can find it at the install path of your eclipse. For example, paht:D:\Program Files\eclipse is my eclipse install path and eclipse.ini file is in directory of D:\Program Files\eclipse.
