Spring Secutiry logout not destroying JSESSIONID defined in web-fragment - web

Question

I am using Spring security to secure my rest API. Following are my configurations;
spring-secutiry.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:security="http://www.springframework.org/schema/security"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.1.xsd
http://www.springframework.org/schema/security
http://www.springframework.org/schema/security/spring-security-3.1.xsd">
<security:http auto-config="true">
<!-- Authentication Type and Intercepter Configurations -->
<security:http-basic />
<security:intercept-url pattern="/**" />
<security:anonymous enabled="false" />
<security:session-management invalid-session-url="/">
<security:concurrency-control max-sessions="1" />
</security:session-management>
<security:logout logout-url="/signOff" invalidate-session="true"
delete-cookies="JSESSIONID" logout-success-url="/" />
</security:http>
<bean id="myAuthenticationProvider"
class="com.myauthenticator.spring.secutiry.MyAuthenticationProvider" />
<security:authentication-manager>
<security:authentication-provider ref="myAuthenticationProvider" />
</security:authentication-manager>
</beans>
There is no such implementation for custom logout. I am expecting Spring to intercept call to /signOff and destroys token and redirect me to / because of the configuration in logout-success-url which should challenge for a BASIC auth once more but its loading my home page.
It seems like my spring configurations are not correct i.e. not all calls are intercepted by Spring filter. I have following configurations in my web.xml to priorities my web-fragment which contains my Spring Security Filter;
web.xml
<absolute-ordering>
<name>MyAuthenticator</name>
<others/>
</absolute-ordering>
Note: My filter and custom authentication are implemented as a web-fragment which looks like as follows;
web-fragement.xml
<web-fragment
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
xmlns:webfragment="http://java.sun.com/xml/ns/javaee/web-fragment_3_0.xsd"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-fragment_3_0.xsd"
id="T24Authenticator" version="3.0">
<display-name>T24 Authentication Provider</display-name>
<name>MyAuthenticator</name>
<!-- Spring Security -->
<filter>
<filter-name>springSecurityFilterChain</filter-name>
<filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
</filter>
<filter-mapping>
<filter-name>springSecurityFilterChain</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
.....
I think there is something wrong with my configurations! But I can't spot it, can anyone?
