"JBoss cache. 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(); } } >From time to time, this test output "error", which i run from static void mai. >1 of 3 runs return "error" msg, node simply return "null". I can't reproduce >it on every machine -------------------------------------------------------------- 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&containerType=14&container=2052]
