Invalid place to record expectations on jmockit

I have such error message

java.lang.IllegalStateException: Invalid place to record expectations

On this method

private void expectNextNotExist() throws SQLException {
    new Expectations() {
        {
            resultSet.next();
            returns(false);
            times = 1;
        }
    };
}

Where resultSet is java.sql.ResultSet. I have found some similar issues, but they didn't help me. I'm using Junit 4, Jmockit 1.11. How should I rewrite this method?
