[hibernate-issues] [Hibernate-JIRA] Resolved: (HHH-4757) nextTimestamp not precise enough for Infinispan 2LC

nextTimestamp not precise enough for Infinispan 2LC --------------------------------------------------- Key: HHH-4757 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4757 Project: Hibernate Core Issue Type: Bug Components: caching (L2) Affects Versions: 3.5.0-Beta-2 Reporter: Galder Zamarreno Assignee: Galder Zamarreno oing some tests we discovered that with Infinispan cached querys are not recognized as UpToDate when the query call (= the chache put) happens within 100ms after the last UpdateTimestamps invalidation. This is because Infinispan defines a rather low timestamp granular precision, indeed ehcache's precision goes into milliseconds. InfinispanRegionFactory.java: public long nextTimestamp() { return System.currentTimeMillis() / 100; } EHCache-TimeStamper: public static long next() { synchronized(Timestamper.class) { long newTime = System.currentTimeMillis() << BIN_DIGITS; if (time<newTime) { time = newTime; counter = 0; } else if (counter < ONE_MS - 1 ) { counter++; } return time + counter; } } regards G.D.
