Spring Security add Authorities
<p>We have migrated from Spring security 3.0.5 to 3.2.5. We were using below code for adding authorities.</p>

<pre><code> UserDetails loadedUser = new UserDetails();
 loadedUser.getAuthorities().add(new GrantedAuthorityImpl("ROLE_ADMIN"));
</code></pre>

<p>Now this code is giving below error</p>

<p>The method add(capture#1-of ? extends GrantedAuthority) in the type Collection is not applicable for the arguments (GrantedAuthorityImpl)</p>

<p>Can some one please help me with this issue ?</p>
