My approach was to create hundred thousand local collections and populate them with random strings, something like this:

    SecureRandom random = new SecureRandom();
    for(int i = 0 ; i < 100000 ; i++){
        HashMap<String, String> map = new HashMap<String, String>();
        for(int j = 0 ; j < 30 ; j++){
            map.put(new BigInteger(130, random).toString(32), new BigInteger(130, random).toString(32));
        }
    }

I have provided -XX:+UseGCOverheadLimit jvm parameter too, but can not get the error. Is there any easy and reliable way/hack to get this error?
