             Summary: Cache::start doesn't setup CommandInitializer in ComponentRegistry when used with Query
                 Key: ISPN-2232
                 URL: https://issues.jboss.org/browse/ISPN-2232
             Project: Infinispan
          Issue Type: Feature Request
          Components: Configuration, Querying
    Affects Versions: 5.2.0.ALPHA2
            Reporter: Ales Justin
            Assignee: Galder Zamarreño
             Fix For: 5.2.0.Alpha3


When re-starting existing stopped cache, NPE is thrown:

23:10:27,160 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[default-host]] (http-/192.168.1.101:8080-2) Exception sending request initialized lifecycle event to listener instance of class org.jboss.capedwarf.appidentity.GAEListener: java.lang.NullPointerException

This is the code I added:

   private static <K, V> Cache<K, V> checkCache(String cacheName) {
       final Cache<K, V> cache = cacheManager.getCache(cacheName, false);
       if (cache != null) {
           final ComponentStatus status = cache.getStatus();
           if (status != ComponentStatus.INITIALIZING && status != ComponentStatus.RUNNING) {
               cache.start();
           }
       }
       return cache;
   }
