LoadersConfigurationBuilder does not clear existing stores on read() -------------------------------------------------------------------- Key: ISPN-3152 URL: https://issues.jboss.org/browse/ISPN-3152 Project: Infinispan Issue Type: Bug Components: Configuration Affects Versions: 5.2.1.Final Reporter: Marta Sedlakova Assignee: Tristan Tarrant Fix For: 5.3.0.Final Hello, I am upgrading infinispan configuration and I have following problem: In old configuration, we use: Configuration config; JdbmCacheStoreConfig storeConfig = new JdbmCacheStoreConfig(); storeConfig.setLocation(location); storeConfig.setCacheLoaderClassName("org.infinispan.loaders.jdbm.JdbmCacheStore"); storeConfig.setFetchPersistentState(true); storeConfig.setIgnoreModifications(false); storeConfig.setPurgeOnStartup(false); config = lc.addCacheLoader(storeConfig).build(); manager = new DefaultCacheManager(new GlobalConfiguration(), config); Configuration c = manager.getDefaultConfiguration(); c.setEvictionMaxEntries(maxEntries); c.setExpirationLifespan(lifespan); manager.defineConfiguration(name, c); And this works fine. Now I am updating to new configuration: ConfigurationBuilder configuration = new ConfigurationBuilder(); configuration.invocationBatching().enable(); JdbmCacheStoreConfigurationBuilder builder = new JdbmCacheStoreConfigurationBuilder(configuration.loaders()); builder.location(location).fetchPersistentState(true); configuration.loaders().addStore(builder); manager = new DefaultCacheManager(new GlobalConfigurationBuilder().build(), configuration.build()); And I want to change some properties from previous default configuration for named cache: ConfigurationBuilder builder = new ConfigurationBuilder(); builder.read(manager.getDefaultCacheConfiguration()); builder.eviction().maxEntries(maxEntries)); builder.expiration().lifespan(lifespan); manager.defineConfiguration(name, builder.build()); Cache<String, Object> cache = manager.getCache(name); cache.start(); But I got following exception: org.infinispan.CacheException: Unable to invoke method public void org.infinispan.loaders.CacheLoaderManagerImpl.start() on object of type CacheLoaderManagerImpl at org.infinispan.util.ReflectionUtil.invokeAccessibly(ReflectionUtil.java:205) at org.infinispan.factories.AbstractComponentRegistry$PrioritizedMethod.invoke(AbstractComponentRegistry.java:883) at org.infinispan.factories.AbstractComponentRegistry.invokeStartMethods(AbstractComponentRegistry.java:654) at org.infinispan.factories.AbstractComponentRegistry.internalStart(AbstractComponentRegistry.java:643) at org.infinispan.factories.AbstractComponentRegistry.start(AbstractComponentRegistry.java:546) at org.infinispan.factories.ComponentRegistry.start(ComponentRegistry.java:199) at org.infinispan.CacheImpl.start(CacheImpl.java:559) at org.infinispan.manager.DefaultCacheManager.wireAndStartCache(DefaultCacheManager.java:686) at org.infinispan.manager.DefaultCacheManager.createCache(DefaultCacheManager.java:649) at org.infinispan.manager.DefaultCacheManager.getCache(DefaultCacheManager.java:545) at eu.ysoft.cache.ifspn.replicator.IfspnReplicationBuffer.start(IfspnReplicationBuffer.java:117) at eu.ysoft.cache.replicator.ReplicatorImpl.start(ReplicatorImpl.java:373) at eu.ysoft.cache.replicator.ReplicatorImpl.start(ReplicatorImpl.java:233) at eu.ysoft.cache.ifspn.replicator.helpers.IfspnReplicationClient.start(IfspnReplicationClient.java:46) at eu.ysoft.cache.ifspn.replicator.functional.IfspnTestSimpleReplications.init(IfspnTestSimpleReplications.java:54) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.testng.internal.MethodInvocationHelper.invokeMethod(MethodInvocationHelper.java:80) at org.testng.internal.Invoker.invokeConfigurationMethod(Invoker.java:525) at org.testng.internal.Invoker.invokeConfigurations(Invoker.java:202) at org.testng.internal.Invoker.invokeMethod(Invoker.java:613) at org.testng.internal.Invoker.invokeTestMethod(Invoker.java:842) at org.testng.internal.Invoker.invokeTestMethods(Invoker.java:1166) at org.testng.internal.TestMethodWorker.invokeTestMethods(TestMethodWorker.java:125) at org.testng.internal.TestMethodWorker.run(TestMethodWorker.java:109) at org.testng.TestRunner.runWorkers(TestRunner.java:1178) at org.testng.TestRunner.privateRun(TestRunner.java:757) at org.testng.TestRunner.run(TestRunner.java:608) at org.testng.SuiteRunner.runTest(SuiteRunner.java:334) at org.testng.SuiteRunner.runSequentially(SuiteRunner.java:329) at org.testng.SuiteRunner.privateRun(SuiteRunner.java:291) at org.testng.SuiteRunner.run(SuiteRunner.java:240) at org.testng.SuiteRunnerWorker.runSuite(SuiteRunnerWorker.java:52) at org.testng.SuiteRunnerWorker.run(SuiteRunnerWorker.java:86) at org.testng.TestNG.runSuitesSequentially(TestNG.java:1158) at org.testng.TestNG.runSuitesLocally(TestNG.java:1083) at org.testng.TestNG.run(TestNG.java:999) at org.testng.remote.RemoteTestNG.run(RemoteTestNG.java:111) at org.testng.remote.RemoteTestNG.initAndRun(RemoteTestNG.java:203) at org.testng.remote.RemoteTestNG.main(RemoteTestNG.java:174) at org.testng.RemoteTestNGStarter.main(RemoteTestNGStarter.java:111) Caused by: org.infinispan.CacheException: Unable to start cache loaders at org.infinispan.loaders.CacheLoaderManagerImpl.start(CacheLoaderManagerImpl.java:160) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.infinispan.util.ReflectionUtil.invokeAccessibly(ReflectionUtil.java:203) ... 42 more Caused by: java.lang.Exception: Invalid cache loader configuration!!
