Spring security custom login redirection conflict

I have created a custom login form using spring security some point of time it working as perfect but some times after login URL is redirecting to css or images or js folders. After i hit refresh it working fine, i dont know what is wrong with my spring security.

Custom login page

<form:form class="form-vertical login-form"   action="j_spring_security_check" method="post">
        <h3 class="form-title">Login to your account</h3>
        <input  type="text" autocomplete="off" placeholder="Username" name="j_username"/>
        <input  type="password" autocomplete="off" placeholder="Password" name="j_password"/>

        <font color="red">
           <span>${sessionScope["SPRING_SECURITY_LAST_EXCEPTION"].message}</span>
        </font>

    </form:form>
