jiriprox: IOOBE when performing instant rename 

Steps to reproduce:
1) have a code:
public class ClassARen {
    
    public int getX() {
        return 1;
    }

    public void use() {
        int x = getX();
    }
}

2) press Insert to get to override mode
3) start renaming on the first 'getX'
4) put cursor at the 'e'  inside 'e'
5) type new character
-> exception is thrown
