Exception when handling command SingleRpcCommand ------------------------------------------------ Key: ISPN-3536 URL: https://issues.jboss.org/browse/ISPN-3536 Project: Infinispan Issue Type: Bug Components: Cross-Site Replication Affects Versions: 5.3.0.Final, 6.0.0.Alpha4 Environment: Linux ip-10-252-170-214 3.4.43-43.43.amzn1.x86_64 #1 SMP Mon May 6 18:04:41 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux java version "1.6.0_24" OpenJDK Runtime Environment (IcedTea6 1.11.11.90) (amazon-62.1.11.11.90.55.amzn1-x86_64) OpenJDK 64-Bit Server VM (build 20.0-b12, mixed mode) Reporter: Mark De Leon Assignee: Mircea Markus Attachments: pearson-clustered-xsite-bos.xml, pearson-clustered-xsite-va.xml The following can be referenced from forum post by Chris Riley ISPN000071 Trying to perform an insert of a cache value into a distributed cache that is replicated via Cross Site Replication in JBoss 6.0.0.Alpha4. The cross site replication has two nodes in the global cluster. When a value is put on the local site we get the following error on the remote site. We just upgraded to 6.0.0.Alpha4 because of JIRA ISSUE ISPN-3346, which we reproduced in 5.3.0.Final. I have attached our jboss configuration file for review. 17:22:41,798 WARN [org.infinispan.remoting.transport.jgroups.CommandAwareRpcDispatcher] (Incoming-2,shared=tcp) ISPN000071: Caught exception when handling command SingleRpcCommand{cacheName='importantCache', command=PutKeyValueCommand{key=1, value=[B@363f983f, flags=null, putIfAbsent=false, metadata=MimeMetadata(contentType=text/plain), successful=true, ignorePreviousValue=false}}: java.lang.NullPointerException at org.infinispan.xsite.BackupReceiverRepositoryImpl.isBackupForRemoteCache(BackupReceiverRepositoryImpl.java:112) [infinispan-core-6.0.0.Alpha4.jar:6.0.0.Alpha4] at org.infinispan.xsite.BackupReceiverRepositoryImpl.getBackupCacheManager(BackupReceiverRepositoryImpl.java:95) [infinispan-core-6.0.0.Alpha4.jar:6.0.0.Alpha4] at org.infinispan.xsite.BackupReceiverRepositoryImpl.handleRemoteCommand(BackupReceiverRepositoryImpl.java:67) [infinispan-core-6.0.0.Alpha4.jar:6.0.0.Alpha4] at org.infinispan.remoting.transport.jgroups.CommandAwareRpcDispatcher.executeCommandFromRemoteSite(CommandAwareRpcDispatcher.java:234) [infinispan-core-6.0.0.Alpha4.jar:6.0.0.Alpha4] at org.infinispan.remoting.transport.jgroups.CommandAwareRpcDispatcher.handle(CommandAwareRpcDispatcher.java:209) [infinispan-core-6.0.0.Alpha4.jar:6.0.0.Alpha4] at org.jgroups.blocks.RequestCorrelator.handleRequest(RequestCorrelator.java:460) [jgroups-3.4.0.Alpha1.jar:3.4.0.Alpha1] at org.jgroups.blocks.RequestCorrelator.receiveMessage(RequestCorrelator.java:377) [jgroups-3.4.0.Alpha1.jar:3.4.0.Alpha1] at org.jgroups.blocks.RequestCorrelator.receive(RequestCorrelator.java:247) [jgroups-3.4.0.Alpha1.jar:3.4.0.Alpha1] at org.jgroups.blocks.MessageDispatcher$ProtocolAdapter.up(MessageDispatcher.java:665) [jgroups-3.4.0.Alpha1.jar:3.4.0.Alpha1] at org.jgroups.blocks.mux.MuxUpHandler.up(MuxUpHandler.java:130) [jgroups-3.4.0.Alpha1.jar:3.4.0.Alpha1] at org.jgroups.JChannel.up(JChannel.java:719) [jgroups-3.4.0.Alpha1.jar:3.4.0.Alpha1] at org.jgroups.stack.ProtocolStack.up(ProtocolStack.java:1002) [jgroups-3.4.0.Alpha1.jar:3.4.0.Alpha1] at org.jgroups.protocols.relay.RELAY2.deliver(RELAY2.java:612) [jgroups-3.4.0.Alpha1.jar:3.4.0.Alpha1] at org.jgroups.protocols.relay.RELAY2.route(RELAY2.java:508) [jgroups-3.4.0.Alpha1.jar:3.4.0.Alpha1] at org.jgroups.protocols.relay.RELAY2.handleMessage(RELAY2.java:483) [jgroups-3.4.0.Alpha1.jar:3.4.0.Alpha1] at org.jgroups.protocols.relay.RELAY2.handleRelayMessage(RELAY2.java:461) [jgroups-3.4.0.Alpha1.jar:3.4.0.Alpha1] at org.jgroups.protocols.relay.Relayer$Bridge.receive(Relayer.java:263) [jgroups-3.4.0.Alpha1.jar:3.4.0.Alpha1] at org.jgroups.JChannel.up(JChannel.java:749) [jgroups-3.4.0.Alpha1.jar:3.4.0.Alpha1] at org.jgroups.stack.ProtocolStack.up(ProtocolStack.java:1006) [jgroups-3.4.0.Alpha1.jar:3.4.0.Alpha1] at org.jgroups.stack.Protocol.up(Protocol.java:406) [jgroups-3.4.0.Alpha1.jar:3.4.0.Alpha1] at org.jgroups.protocols.FRAG2.up(FRAG2.java:195) [jgroups-3.4.0.Alpha1.jar:3.4.0.Alpha1] at org.jgroups.protocols.FlowControl.up(FlowControl.java:439) [jgroups-3.4.0.Alpha1.jar:3.4.0.Alpha1] at org.jgroups.protocols.FlowControl.up(FlowControl.java:439) [jgroups-3.4.0.Alpha1.jar:3.4.0.Alpha1] at org.jgroups.stack.Protocol.up(Protocol.java:406) [jgroups-3.4.0.Alpha1.jar:3.4.0.Alpha1] at org.jgroups.protocols.pbcast.STABLE.up(STABLE.java:304) [jgroups-3.4.0.Alpha1.jar:3.4.0.Alpha1] at org.jgroups.protocols.UNICAST.removeAndDeliver(UNICAST.java:748) [jgroups-3.4.0.Alpha1.jar:3.4.0.Alpha1] at org.jgroups.protocols.UNICAST.handleBatchReceived(UNICAST.java:704) [jgroups-3.4.0.Alpha1.jar:3.4.0.Alpha1] at org.jgroups.protocols.UNICAST.up(UNICAST.java:454) [jgroups-3.4.0.Alpha1.jar:3.4.0.Alpha1] at org.jgroups.stack.Protocol.up(Protocol.java:406) [jgroups-3.4.0.Alpha1.jar:3.4.0.Alpha1] at org.jgroups.stack.Protocol.up(Protocol.java:406) [jgroups-3.4.0.Alpha1.jar:3.4.0.Alpha1] at org.jgroups.protocols.FD.up(FD.java:274) [jgroups-3.4.0.Alpha1.jar:3.4.0.Alpha1] at org.jgroups.stack.Protocol.up(Protocol.java:406) [jgroups-3.4.0.Alpha1.jar:3.4.0.Alpha1] at org.jgroups.protocols.MERGE2.up(MERGE2.java:223) [jgroups-3.4.0.Alpha1.jar:3.4.0.Alpha1] at org.jgroups.stack.Protocol.up(Protocol.java:406) [jgroups-3.4.0.Alpha1.jar:3.4.0.Alpha1] at org.jgroups.stack.Protocol.up(Protocol.java:406) [jgroups-3.4.0.Alpha1.jar:3.4.0.Alpha1] at org.jgroups.protocols.TP.passBatchUp(TP.java:1409) [jgroups-3.4.0.Alpha1.jar:3.4.0.Alpha1] at org.jgroups.protocols.TP$BatchHandler.run(TP.java:1564) [jgroups-3.4.0.Alpha1.jar:3.4.0.Alpha1] at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1110) [rt.jar:1.6.0_24] at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:603) [rt.jar:1.6.0_24] at java.lang.Thread.run(Thread.java:679) [rt.jar:1.6.0_24]
