Tested with the following piece of code which should hava all edge cases. Works fine :

// should not be commented out
char c = '/*';
String s = "/* some stupid stuff */";

long test(REPLACED k){ /* only this should be commented out */
    if(REPLACED)
        return REPLACED;
    if(REPLACED)
        return REPLACED;
    /* this should be commented out
    if(REPLACED){
        if(REPLACED)
            return REPLACED;
        if(REPLACED)
            return (REPLACED);
    }
   */ this should not
    return 0;
}
