    [ https://issues.jboss.org/browse/ISPN-3819?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12990273#comment-12990273 ] 

Gustavo Fernandes commented on ISPN-3819:
-----------------------------------------

Apparently there is a competition to register ScopedKeys into the Cluster Registry. The issue can be easily reproducible 50% of the time by adding a Random wait in the class QueryInterceptor at line 260, so that it is easier for 2 or more threads to try to insert the same key in the ClusterRegisty at approximately the same time:
 
{code}
  for (Class<?> type : classes) {
         if (!clusterRegistry.containsKey(type)) {
            try {
               Thread.sleep(new Random().nextInt(500));
            } catch (InterruptedException e) {
               e.printStackTrace(); 
            }
            if (toAdd==null)
               toAdd = new ArrayList<Class<?>>(classes.length);
            toAdd.add(type);
         }
      }
{code}
