> In the WSO2 Mashup Server [1] we use rampart to secure some backend services using UT. We ran a load test where a user logs in (the login service is secured via UT) and adds a user. When a user is added hes details are also added to the token store so that he can login too. When we ran the above scenario we got a java.util.ConcurrentModificationException. You can refer to the JIRA at [2]. The issue is that when reading the class SimpleTokenStore gets a iterator on a map and then when a user is added details are added to this map. When this happens concurrently the above issue occurs.
