      <c:if test="${fn:contains( ${authority} , ROLE_ADMIN) }">

      </c:if>
</c:forEach>

There are 2 problems:

  1. You should not nest EL expressions. Just reference the EL variable the usual way.

    <c:if test="${fn:contains(authority, ROLE_ADMIN)}">

  2. It's not clear from the question context if ROLE_ADMIN is already in the EL scope. But you need to know that you cannot reference constants in EL. If it's for example an enum, then it's good to know that they are just evaluated as String. You need to quote it then.

    <c:if test="${fn:contains(authority, 'ROLE_ADMIN')}">

You're missing a closing ")" in your if test:

 <c:forEach var="authority" items="#{SPRING_SECURITY_CONTEXT.authentication.principal.authorities}">

      <c:if test="${fn:contains( {$authority} , ROLE_ADMIN ) }">

      </c:if>
</c:forEach>
