title: Spring versions incompatibility
body: <p>I'm working on a project where we use Spring and Spring Security.</p>
  
  <p>Our current Spring version is <code>4.0.6.RELEASE</code> and our Spring Security version is <code>4.0.0.M1</code>. I try to migrate to higher version of Spring Security <code>4.0.2 Release</code> but when I run my web app some functionality throws <code>NoSuchMethodError</code>. I read that this may be incompatibility of versions. My question is what is the best Security for Spring's current's version?</p>
