java.lang.ClassCastException: [B cannot be cast to org.infinispan.container.entries.CacheEntry ---------------------------------------------------------------------------------------------- Key: ISPN-5449 URL: https://issues.jboss.org/browse/ISPN-5449 Project: Infinispan Issue Type: Bug Affects Versions: 7.2.1.Final Reporter: Enrico Olivelli Assignee: William Burns Fix For: 7.2.2.Final, 8.0.0.Alpha1 Hi, I'm going to upgrade to Infinspan 7.2.1final but I got into a showstopper. This error occours very frequently and the cluster becomes not usable. In dev enviroment I'm using only Java HotRod clients and 3 Java HotRod Servers. When I put a "byte[]" in a cache then the following error occurs. Using only one Hotrod server the error does not occur. {code} ERROR interceptors.InvocationContextInterceptor: ISPN000136: Execution error java.lang.ClassCastException: [B cannot be cast to org.infinispan.container.entries.CacheEntry at org.infinispan.interceptors.compat.BaseTypeConverterInterceptor.visitGetCacheEntryCommand(BaseTypeConverterInterceptor.java:118) at org.infinispan.commands.read.GetCacheEntryCommand.acceptVisitor(GetCacheEntryCommand.java:39) at org.infinispan.interceptors.base.CommandInterceptor.invokeNextInterceptor(CommandInterceptor.java:97) at org.infinispan.interceptors.InvocationContextInterceptor.handleAll(InvocationContextInterceptor.java:102) at org.infinispan.interceptors.InvocationContextInterceptor.handleDefault(InvocationContextInterceptor.java:71) at org.infinispan.commands.AbstractVisitor.visitGetCacheEntryCommand(AbstractVisitor.java:91) at org.infinispan.commands.read.GetCacheEntryCommand.acceptVisitor(GetCacheEntryCommand.java:39) at org.infinispan.interceptors.InterceptorChain.invoke(InterceptorChain.java:336) at org.infinispan.cache.impl.CacheImpl.getCacheEntry(CacheImpl.java:437) at org.infinispan.cache.impl.DecoratedCache.getCacheEntry(DecoratedCache.java:547) at org.infinispan.server.hotrod.CacheDecodeContext.get(CacheDecodeContext.scala:180) at org.infinispan.server.hotrod.HotRodDecoder.org$infinispan$server$hotrod$HotRodDecoder$$decodeKey(HotRodDecoder.scala:103) at org.infinispan.server.hotrod.HotRodDecoder$$anonfun$decode$1.apply$mcV$sp(HotRodDecoder.scala:48) at org.infinispan.server.hotrod.HotRodDecoder$$anon$1.run(HotRodDecoder.scala:206) at org.infinispan.server.hotrod.HotRodDecoder$$anon$1.run(HotRodDecoder.scala:205) at org.infinispan.security.Security.doAs(Security.java:143) at org.infinispan.server.hotrod.HotRodDecoder.wrapSecurity(HotRodDecoder.scala:205) at org.infinispan.server.hotrod.HotRodDecoder.decode(HotRodDecoder.scala:45) at io.netty.handler.codec.ReplayingDecoder.callDecode(ReplayingDecoder.java:370) at io.netty.handler.codec.ByteToMessageDecoder.channelRead(ByteToMessageDecoder.java:168) at org.infinispan.server.hotrod.HotRodDecoder.org$infinispan$server$core$transport$StatsChannelHandler$$super$channelRead(HotRodDecoder.scala:31) at org.infinispan.server.core.transport.StatsChannelHandler$class.channelRead(StatsChannelHandler.scala:32) at org.infinispan.server.hotrod.HotRodDecoder.channelRead(HotRodDecoder.scala:31) .... {code} Cache Server configuration: {code} Configuration wildcard = new ConfigurationBuilder() .locking().lockAcquisitionTimeout(lockAcquisitionTimeout) .concurrencyLevel(10000) .isolationLevel(IsolationLevel.READ_COMMITTED) .useLockStriping(true) .clustering() .cacheMode(CacheMode.DIST_SYNC) .l1().lifespan(l1ttl).enable() .hash().numOwners(numOwners) .capacityFactor(capacityFactor) .partitionHandling().enabled(false) .stateTransfer().awaitInitialTransfer(false) .timeout(initialTransferTimeout).fetchInMemoryState(false) .storeAsBinary().enabled(true) .storeKeysAsBinary(false).storeValuesAsBinary(false) .jmxStatistics().enable() .unsafe().unreliableReturnValues(true) // put e remove non ritornano il valore precedente, tanto a noi non interessa .compatibility().enable() .build(); {code} Hotrod Endpoint: {code} HotRodServerConfigurationBuilder configBuilder = new HotRodServerConfigurationBuilder() .host(address) .port(port); hotrodserver.start(configBuilder .build(), manager); {code} Client side config: {code} org.infinispan.client.hotrod.configuration.ConfigurationBuilder clientBuilder = new org.infinispan.client.hotrod.configuration.ConfigurationBuilder().forceReturnValues(false); clientBuilder.nearCache().mode(NearCacheMode.LAZY).maxEntries(10000); //(for each server....) clientBuilder.addServer().host(serveraddress).port(serverport); {code} {code} RemoteCacheManager remoteCacheManager = new RemoteCacheManager(clientBuilder.build()); {code}
