> After having authenticated via JASPIC, requesting the current {{Subject}} via JACC and then using that for permission checks fails.
> For instance the following code will always set {{hasAccess}} to false given that "/protected/*" requires a role and the authenticated user is in that role:
> {code:java}
> Subject subject = (Subject) PolicyContext.getContext("javax.security.auth.Subject.container");
>  
> boolean hasAccess = Policy.getPolicy().implies(
>     new ProtectionDomain(
>         new CodeSource(null, (Certificate[]) null),
>         null, null, 
>         subject.getPrincipals().toArray(new Principal[subject.getPrincipals().size()])
>     ),
>     new WebResourcePermission("/protected/Servlet", "GET"))
> ;
> {code}
> As it appears, the problem originates from the fact that {{subject.getPrincipals()}} does not contain the roles.
> This can be traced back to {{org.jboss.security.auth.callback.JASPICallbackHandler.handleCallBack}}, where it becomes clear that the roles are only put into the "util", but not in the "authenticatedSubject":
> {code:java}
> String[] rolesArray = groupPrincipalCallback.getGroups();
> int sizeOfRoles = rolesArray != null ? rolesArray.length : 0;
>  
> if( sizeOfRoles > 0 )
> {
>   List<Role> rolesList = new ArrayList<Role>();
>   for( int i = 0; i < sizeOfRoles ; i++ )
>   {
>      Role role = new SimpleRole( rolesArray[ i ] );
>      rolesList.add( role );
>   }
>   RoleGroup roles = new SimpleRoleGroup( SecurityConstants.ROLES_IDENTIFIER, rolesList );
>   // if the current security context already has roles, we merge them with the incoming roles.
>   RoleGroup currentRoles = currentSC.getUtil().getRoles();
>   // *** ROLES ARE ONLY SET HERE ***
>   if (currentRoles != null) {
>       currentRoles.addAll(roles.getRoles());
>   }
>   else {
>       currentSC.getUtil().setRoles( roles );
>   }
> } 
> // *** BELOW THIS LINE ROLES ARE NOT REFERENCED ANYMORE
> // *** SUBJECT IS NOT POPULATED WITH ANY ROLE INFO 
> Subject subject = groupPrincipalCallback.getSubject();
> if( subject != null )
> {
>    // if the current security context already has an associated subject, we merge it with the incoming subject.
>    Subject currentSubject = currentSC.getSubjectInfo().getAuthenticatedSubject();
>    if (currentSubject != null) {
>        subject.getPrincipals().addAll(currentSubject.getPrincipals());
>        subject.getPublicCredentials().addAll(currentSubject.getPublicCredentials());
>        subject.getPrivateCredentials().addAll(currentSubject.getPrivateCredentials());
>    }
>    currentSC.getSubjectInfo().setAuthenticatedSubject(subject);
> }
> {code}
