Charles Akalugwu [https://community.jboss.org/people/canotech] created the discussion "Hibernate-Infinispan NullPointerException in CacheKey.equals method" To view the discussion, visit: https://community.jboss.org/message/751412#751412 -------------------------------------------------------------- I am trying to use Infinispan 5.1.5 Final in my app. I use the following environment: JBoss AS 7.1.1 Final Hibernate Core 4.1.5.SP1 Hibernate Search 4.1.1 Final Infinispan 5.1.5 Final JBoss Seam 2.3.0 Beta2 At application startup, I try to see if the admin user accounts exist and if they don't I create them. As follows: private void initDefaultUsersAndRoles(){         log.info("Initializing Default Roles And Passwords");         Role adminRole = roleDAO.getByName("administrator");         if (adminRole == null) {            //create new admin role         } *User admin = userDAO.findByUsername("admin ");*         if (admin  == null) {             //create new admin user         } } I get an exception in the userDAO.findByUsername method which is shown below: public User findByUsername(String username) {                     User user;                     try{                               Query q = getEm().createQuery("SELECT e FROM "                                                   + entityClass.getName() + " e WHERE username = :username");                               q.setParameter("username", username );                               q.setHint("org.hibernate.cacheable", "true" );                               user = (User) q.getSingleResult();                     }                     catch( NoResultException e ){                               return null;                     }                     return user; } Upon execution of user = (User) q.getSingleResult() I get the following error: 18:44:31,283 INFO  [org.hibernate.search.Version] (MSC service thread 1-8) HSEARCH000034: Hibernate Search 4.1.1.Final 18:44:52,097 ERROR
