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)

}
return cache;
}
