SingletonStoreCacheLoader does not work with MVCC ------------------------------------------------- Key: JBCACHE-1561 URL: https://jira.jboss.org/jira/browse/JBCACHE-1561 Project: JBoss Cache Issue Type: Bug Security Level: Public(Everyone can see) Affects Versions: 3.2.1.GA Reporter: Mircea Markus Assignee: Galder Zamarreno Fix For: 3.2.2.GA For some reason SingletonStoreCacheLoaderTest had been configured with PL caches: cache1.getConfiguration().setNodeLockingScheme(NodeLockingScheme.PESSIMISTIC); cache2.getConfiguration().setNodeLockingScheme(NodeLockingScheme.PESSIMISTIC); cache3.getConfiguration().setNodeLockingScheme(NodeLockingScheme.PESSIMISTIC); Removing these makes caches use MVCC which in turn makes testPutCacheLoaderWithPush throw: java.util.concurrent.ExecutionException: java.lang.UnsupportedOperationException: Not supported in UnversionedNode at java.util.concurrent.FutureTask$Sync.innerGet(FutureTask.java:252) at java.util.concurrent.FutureTask.get(FutureTask.java:111) at org.jboss.cache.loader.SingletonStoreCacheLoaderTest.waitForPushStateCompletion(SingletonStoreCacheLoaderTest.java:273) at org.jboss.cache.loader.SingletonStoreCacheLoaderTest.testPutCacheLoaderWithPush(SingletonStoreCacheLoaderTest.java:160) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:616) at org.testng.internal.MethodHelper.invokeMethod(MethodHelper.java:644) at org.testng.internal.Invoker.invokeMethod(Invoker.java:546) at org.testng.internal.Invoker.invokeTestMethod(Invoker.java:700) at org.testng.internal.Invoker.invokeTestMethods(Invoker.java:1002) at org.testng.internal.TestMethodWorker.invokeTestMethods(TestMethodWorker.java:137) at org.testng.internal.TestMethodWorker.run(TestMethodWorker.java:121) at org.testng.TestRunner.runWorkers(TestRunner.java:909) at org.testng.TestRunner.privateRun(TestRunner.java:618) at org.testng.TestRunner.run(TestRunner.java:499) at org.testng.SuiteRunner.runTest(SuiteRunner.java:332) at org.testng.SuiteRunner.runSequentially(SuiteRunner.java:327) at org.testng.SuiteRunner.privateRun(SuiteRunner.java:299) at org.testng.SuiteRunner.run(SuiteRunner.java:204) at org.testng.TestNG.createAndRunSuiteRunners(TestNG.java:915) at org.testng.TestNG.runSuitesLocally(TestNG.java:879) at org.testng.TestNG.run(TestNG.java:787) at org.testng.remote.RemoteTestNG.run(RemoteTestNG.java:73) at org.testng.remote.RemoteTestNG.main(RemoteTestNG.java:124) Caused by: java.lang.UnsupportedOperationException: Not supported in UnversionedNode at org.jboss.cache.AbstractNode.getChildrenDirect(AbstractNode.java:270) at org.jboss.cache.invocation.NodeInvocationDelegate.getChildrenDirect(NodeInvocationDelegate.java:164) at org.jboss.cache.loader.SingletonStoreCacheLoader.pushState(SingletonStoreCacheLoader.java:256) at org.jboss.cache.loader.SingletonStoreCacheLoader$2.call(SingletonStoreCacheLoader.java:227) at java.util.concurrent.FutureTask$Sync.innerRun(FutureTask.java:334) at java.util.concurrent.FutureTask.run(FutureTask.java:166) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1110) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:603) at java.lang.Thread.run(Thread.java:636)
