[infinispan-issues] [JBoss JIRA] (ISPN-1922) New configuration API bug hiding a NPE in VersionedEntryWrappingInterceptor

New configuration API bug hiding a NPE in VersionedEntryWrappingInterceptor --------------------------------------------------------------------------- Key: ISPN-1922 URL: https://issues.jboss.org/browse/ISPN-1922 Project: Infinispan Issue Type: Bug Components: Configuration Affects Versions: 5.1.2.FINAL Reporter: Galder Zamarreño Assignee: Galder Zamarreño Labels: versioning Fix For: 5.1.3.CR1, 5.1.3.FINAL While doing ISPN-1367 and converting the internals to new configuration, I've found two bugs. Basically, there's a bug in the new-to-old configuration transformation (ISPN-1922) that makes FlagsEnabledTest pass when it shouldn't. To be precise, that test enables configuration such as: {code}.versioning().enable().scheme(VersioningScheme.SIMPLE){code} But, in the InterceptorChainFactory, needsVersionAwareComponents returns false (configuration.isEnableVersioning() = false): {code}boolean needsVersionAwareComponents = configuration.isTransactionalCache() && configuration.isWriteSkewCheck() && configuration.getTransactionLockingMode() == LockingMode.OPTIMISTIC && configuration.isEnableVersioning();{code} By changing the internals to the config, the configuration.isEnableVersioning() returns true and so FlagsEnabledTest.testWithFlagsSemantics fails with: {code}2012-03-16 15:12:42,337 ERROR [InvocationContextInterceptor] (main) ISPN000136: Execution error java.lang.NullPointerException at org.infinispan.interceptors.VersionedEntryWrappingInterceptor.commitContextEntry(VersionedEntryWrappingInterceptor.java:94) at org.infinispan.interceptors.EntryWrappingInterceptor.commitEntryIfNeeded(EntryWrappingInterceptor.java:271) at org.infinispan.interceptors.EntryWrappingInterceptor.commitContextEntries(EntryWrappingInterceptor.java:182) at org.infinispan.interceptors.VersionedEntryWrappingInterceptor.visitCommitCommand(VersionedEntryWrappingInterceptor.java:87) at org.infinispan.commands.tx.CommitCommand.acceptVisitor(CommitCommand.java:66) at org.infinispan.interceptors.base.CommandInterceptor.invokeNextInterceptor(CommandInterceptor.java:116) at org.infinispan.interceptors.base.CommandInterceptor.handleDefault(CommandInterceptor.java:130) at org.infinispan.commands.AbstractVisitor.visitCommitCommand(AbstractVisitor.java:121) at org.infinispan.interceptors.locking.AbstractTxLockingInterceptor.visitCommitCommand(AbstractTxLockingInterceptor.java:105) at org.infinispan.commands.tx.CommitCommand.acceptVisitor(CommitCommand.java:66) at org.infinispan.interceptors.base.CommandInterceptor.invokeNextInterceptor(CommandInterceptor.java:116) at org.infinispan.interceptors.NotificationInterceptor.visitCommitCommand(NotificationInterceptor.java:65) at org.infinispan.commands.tx.CommitCommand.acceptVisitor(CommitCommand.java:66) at org.infinispan.interceptors.base.CommandInterceptor.invokeNextInterceptor(CommandInterceptor.java:116) at org.infinispan.interceptors.TxInterceptor.visitCommitCommand(TxInterceptor.java:120) at org.infinispan.commands.tx.CommitCommand.acceptVisitor(CommitCommand.java:66) at org.infinispan.interceptors.base.CommandInterceptor.invokeNextInterceptor(CommandInterceptor.java:116) at org.infinispan.interceptors.StateTransferLockInterceptor.handleWithRetries(StateTransferLockInterceptor.java:207) at org.infinispan.interceptors.StateTransferLockInterceptor.visitCommitCommand(StateTransferLockInterceptor.java:120) at org.infinispan.commands.tx.CommitCommand.acceptVisitor(CommitCommand.java:66) at org.infinispan.interceptors.base.CommandInterceptor.invokeNextInterceptor(CommandInterceptor.java:116) at org.infinispan.interceptors.InvocationContextInterceptor.handleAll(InvocationContextInterceptor.java:130) at org.infinispan.interceptors.InvocationContextInterceptor.handleDefault(InvocationContextInterceptor.java:89) at org.infinispan.commands.AbstractVisitor.visitCommitCommand(AbstractVisitor.java:121) at org.infinispan.commands.tx.CommitCommand.acceptVisitor(CommitCommand.java:66) at org.infinispan.interceptors.InterceptorChain.invoke(InterceptorChain.java:345) at org.infinispan.transaction.TransactionCoordinator.commit(TransactionCoordinator.java:182) at org.infinispan.transaction.xa.TransactionXaAdapter.commit(TransactionXaAdapter.java:125) at com.arjuna.ats.internal.jta.resources.arjunacore.XAResourceRecord.topLevelOnePhaseCommit(XAResourceRecord.java:667) at com.arjuna.ats.arjuna.coordinator.BasicAction.onePhaseCommit(BasicAction.java:2283) at com.arjuna.ats.arjuna.coordinator.BasicAction.End(BasicAction.java:1466) at com.arjuna.ats.arjuna.coordinator.TwoPhaseCoordinator.end(TwoPhaseCoordinator.java:98) at com.arjuna.ats.arjuna.AtomicAction.commit(AtomicAction.java:164) at com.arjuna.ats.internal.jta.transaction.arjunacore.TransactionImple.commitAndDisassociate(TransactionImple.java:1165) at com.arjuna.ats.internal.jta.transaction.arjunacore.BaseTransaction.commit(BaseTransaction.java:117) at org.infinispan.CacheImpl.executeCommandAndCommitIfNeeded(CacheImpl.java:955) at org.infinispan.CacheImpl.put(CacheImpl.java:659) at org.infinispan.DecoratedCache.put(DecoratedCache.java:319) at org.infinispan.api.flags.FlagsEnabledTest.testWithFlagsSemantics(FlagsEnabledTest.java:83) 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){code}
