[infinispan-issues] [JBoss JIRA] (ISPN-1418) FileCacheStore throws an IllegalMonitorStateException in FileCacheVamTest

FileCacheStore throws an IllegalMonitorStateException in FileCacheVamTest ------------------------------------------------------------------------- Key: ISPN-1418 URL: https://issues.jboss.org/browse/ISPN-1418 Project: Infinispan Issue Type: Bug Components: Loaders and Stores Affects Versions: 5.0.0.FINAL, 5.0.1.FINAL, 5.1.0.ALPHA2 Reporter: Dan Berindei Assignee: Dan Berindei Priority: Minor Fix For: 5.0.2.FINAL, 5.1.0.BETA1, 5.1.0.FINAL If there are no expired elements the bucket will not be modified and the lock doesn't need to be acquired. We were still releasing the lock though, leading to IllegalMonitorStateExceptions in FileCacheStoreVamTest: 2011-09-25 11:54:46,000 ERROR (testng-FileCacheStoreVamTest) [org.infinispan.test.fwk.UnitTestTestNGListener] Method testLoadAndStoreWithLifespan(org.infinispan.loaders.file.FileCacheStoreVamTest) threw an exception java.lang.IllegalMonitorStateException at java.util.concurrent.locks.ReentrantReadWriteLock$Sync.tryReleaseShared(ReentrantReadWriteLock.java:398) at java.util.concurrent.locks.AbstractQueuedSynchronizer.releaseShared(AbstractQueuedSynchronizer.java:1340) at java.util.concurrent.locks.ReentrantReadWriteLock$ReadLock.unlock(ReentrantReadWriteLock.java:778) at org.infinispan.util.concurrent.locks.StripedLock.releaseLock(StripedLock.java:135) at org.infinispan.loaders.LockSupportCacheStore.unlock(LockSupportCacheStore.java:87) at org.infinispan.loaders.file.FileCacheStore.purgeInternal(FileCacheStore.java:244) at org.infinispan.loaders.AbstractCacheStore$2.run(AbstractCacheStore.java:106) at org.infinispan.util.concurrent.WithinThreadExecutor.execute(WithinThreadExecutor.java:48) at org.infinispan.loaders.AbstractCacheStore.purgeExpired(AbstractCacheStore.java:103) at org.infinispan.loaders.BaseCacheStoreTest.purgeExpired(BaseCacheStoreTest.java:198) at org.infinispan.loaders.BaseCacheStoreTest.testLoadAndStoreWithLifespan(BaseCacheStoreTest.java:151) 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.access$000(SuiteRunner.java:33) at org.testng.SuiteRunner$SuiteWorker.run(SuiteRunner.java:358) at org.testng.internal.thread.ThreadUtil$CountDownLatchedRunnable.run(ThreadUtil.java:142) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1110) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:603) at java.lang.Thread.run(Thread.java:679)
