[Ben Wang (JIRA)]

    [ http://jira.jboss.com/jira/browse/JBCACHE-110?page=comments#action_12343446 ] 
            
Ben Wang commented on JBCACHE-110:
----------------------------------

Currently, I have used an annotation @Reentrant and the following declaration in jboss-aop.xml:

   <!-- This bind the jointpoint to specific in-memory operations. Currently in PojoUtil. -->
   <bind pointcut="execution(*
      @org.jboss.cache.pojo.annotation.Reentrant->toString())">
      <interceptor-ref name="Reentrant"/>
   </bind>

   <!-- Interceptor to perform Pojo level rollback -->
   <interceptor name="Reentrant" class="org.jboss.cache.pojo.interceptors.MethodReentrancyStopperInterceptor"
                scope="PER_INSTANCE"/>

The annotation currently applies only to List, Set, and Map impl now.

> In TreeCacheAOp, certain over-riding will trigger stack overflow. THis is becuase of the recursive field interecption that results. Solution is to detect the field recusion.
