NullPointerException during object unmarshalling ------------------------------------------------ Key: ISPN-630 URL: https://jira.jboss.org/browse/ISPN-630 Project: Infinispan Issue Type: Bug Components: Marshalling Affects Versions: 4.1.0.Final Reporter: Sanne Grinovero Assignee: Galder Zamarreño Fix For: 4.2.0.BETA1, 5.0.0.BETA1 It appears the ExternalizerAdapter was not added to the readers, or that input.readUnsignedByte() reads a wrong identifier value. Not easy to reproduce, get this sometimes under load: Exception in thread "Scarlet/Lucene service thread index reopening thread-1" java.lang.NullPointerException at org.infinispan.marshall.jboss.ConstantObjectTable.readObject(ConstantObjectTable.java:253) at org.jboss.marshalling.river.RiverUnmarshaller.doReadObject(RiverUnmarshaller.java:357) at org.jboss.marshalling.river.RiverUnmarshaller.doReadObject(RiverUnmarshaller.java:207) at org.jboss.marshalling.AbstractUnmarshaller.readObject(AbstractUnmarshaller.java:85) at org.infinispan.marshall.jboss.GenericJBossMarshaller.objectFromObjectStream(GenericJBossMarshaller.java:162) at org.infinispan.marshall.VersionAwareMarshaller.objectFromByteBuffer(VersionAwareMarshaller.java:111) at org.infinispan.marshall.AbstractStreamingMarshaller.objectFromInputStream(AbstractStreamingMarshaller.java:23) at org.infinispan.loaders.jdbc.JdbcUtil.unmarshall(JdbcUtil.java:88) at org.infinispan.loaders.jdbc.stringbased.JdbcStringBasedCacheStore.loadLockSafe(JdbcStringBasedCacheStore.java:298) at org.infinispan.loaders.LockSupportCacheStore.load(LockSupportCacheStore.java:100) at org.infinispan.loaders.decorators.AbstractDelegatingStore.load(AbstractDelegatingStore.java:86) at org.infinispan.interceptors.CacheLoaderInterceptor.loadIfNeeded(CacheLoaderInterceptor.java:138) at org.infinispan.interceptors.CacheLoaderInterceptor.loadIfNeededAndUpdateStats(CacheLoaderInterceptor.java:200) at org.infinispan.interceptors.CacheLoaderInterceptor.visitGetKeyValueCommand(CacheLoaderInterceptor.java:87) at org.infinispan.commands.read.GetKeyValueCommand.acceptVisitor(GetKeyValueCommand.java:58) at org.infinispan.interceptors.base.CommandInterceptor.invokeNextInterceptor(CommandInterceptor.java:118) at org.infinispan.interceptors.base.CommandInterceptor.handleDefault(CommandInterceptor.java:132) at org.infinispan.commands.AbstractVisitor.visitGetKeyValueCommand(AbstractVisitor.java:87) at org.infinispan.commands.read.GetKeyValueCommand.acceptVisitor(GetKeyValueCommand.java:58) at org.infinispan.interceptors.base.CommandInterceptor.invokeNextInterceptor(CommandInterceptor.java:118) at org.infinispan.interceptors.TxInterceptor.enlistReadAndInvokeNext(TxInterceptor.java:171) at org.infinispan.interceptors.TxInterceptor.visitGetKeyValueCommand(TxInterceptor.java:162) at org.infinispan.commands.read.GetKeyValueCommand.acceptVisitor(GetKeyValueCommand.java:58) at org.infinispan.interceptors.base.CommandInterceptor.invokeNextInterceptor(CommandInterceptor.java:118) at org.infinispan.interceptors.CacheMgmtInterceptor.visitGetKeyValueCommand(CacheMgmtInterceptor.java:83) at org.infinispan.commands.read.GetKeyValueCommand.acceptVisitor(GetKeyValueCommand.java:58) at org.infinispan.interceptors.base.CommandInterceptor.invokeNextInterceptor(CommandInterceptor.java:118) at org.infinispan.interceptors.InvocationContextInterceptor.handleAll(InvocationContextInterceptor.java:57) at org.infinispan.interceptors.InvocationContextInterceptor.handleDefault(InvocationContextInterceptor.java:38) at org.infinispan.commands.AbstractVisitor.visitGetKeyValueCommand(AbstractVisitor.java:87) at org.infinispan.commands.read.GetKeyValueCommand.acceptVisitor(GetKeyValueCommand.java:58) at org.infinispan.interceptors.base.CommandInterceptor.invokeNextInterceptor(CommandInterceptor.java:118) at org.infinispan.interceptors.BatchingInterceptor.handleDefault(BatchingInterceptor.java:76) at org.infinispan.commands.AbstractVisitor.visitGetKeyValueCommand(AbstractVisitor.java:87) at org.infinispan.commands.read.GetKeyValueCommand.acceptVisitor(GetKeyValueCommand.java:58) at org.infinispan.interceptors.InterceptorChain.invoke(InterceptorChain.java:273) at org.infinispan.CacheDelegate.get(CacheDelegate.java:200) at org.infinispan.lucene.FileListOperations.getFileList(FileListOperations.java:54)
