[infinispan-issues] [JBoss JIRA] Commented: (ISPN-1244) Cache loses data when another CacheManager joins a cluster

Cache loses data when another CacheManager joins a cluster ---------------------------------------------------------- Key: ISPN-1244 URL: https://issues.jboss.org/browse/ISPN-1244 Project: Infinispan Issue Type: Bug Components: Distributed Cache Affects Versions: 5.0.0.CR7 Environment: single machine (Mac is my case) Reporter: Alex Heneveld Assignee: Manik Surtani I have a test (below) which creates a CacheManager and Cache, sets a value, waits a bit, creates another CacheManager and Cache, then tries to get the value from the first cache. Only it gets null instead -- from both caches! Am new to Infinispan but discussed with Sanne who recommended to file as a bug. Originally discussed in community forum [here|http://community.jboss.org/message/615497]. {code} public void bug() throws InterruptedException { EmbeddedCacheManager cm1 = newCM(); Cache c1 = cm1.getCache("x"); c1.put("key", "value"); Thread.sleep(3000); EmbeddedCacheManager cm2 = newCM(); System.out.println(c1.get("key")); //always says "value" Cache c2 = cm2.getCache("x"); System.out.println(c1.get("key")); //says null sometimes assert c1.get("key") != null : "value at cache 1 was lost"; cm1.stop(); cm2.stop(); } public EmbeddedCacheManager newCM() { GlobalConfiguration gc = GlobalConfiguration.getClusteredDefault(); Configuration cfg = new Configuration().fluent() .mode(Configuration.CacheMode.DIST_SYNC) .hash().numOwners(1) .clustering().l1().disable() .build(); return new DefaultCacheManager(gc, cfg); } {code} (BTW changing to REPL_SYNC, or numOwners(2), it works fine.)
