Concurrency issue" To view the discussion, visit: http://community.jboss.org/message/636461#636461 -------------------------------------------------------------- I'm using +JBossCache 'Malagueta' 3.2.0.GA+ I faced with strange issue in production environment, sometimes writes to jboss are lost. I tried to reproduce this situation with simple java application public static void testCache() {     Cache cache = new DefaultCacheFactory().createCache(false);     cache.create();     cache.start();     final Node node = cache.getRoot().addChild(Fqn.fromString("/child1"));     int threadsCount = 20;     final CyclicBarrier b = new CyclicBarrier(threadsCount);     for (int i = 0; i < threadsCount; i++) {         final long j = i;         new Thread(new Runnable() {             @Override             public void run() {                 try {                     b.await();                     String name = RandomGenerator.getRandomName(4);                     node.put(j, name);                     String nameFromCache = (String) node.get(j);                     if (!name.equals(nameFromCache)) {                         System.out.println("error");                     }                 } catch (Exception e) {                     e.printStackTrace();                 }             }         }).start();     } } -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/636461#636461] Start a new discussion in JBoss Cache at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
