Dan Smith reassigned GEODE-3315: -------------------------------- Assignee: Dan Smith > NullPointerException creating a copy of a client queue when > gemfire.PREFER_SERIALIZED=true > ------------------------------------------------------------------------------------------ > > Key: GEODE-3315 > URL: https://issues.apache.org/jira/browse/GEODE-3315 > Project: Geode > Issue Type: Bug > Components: client queues > Reporter: Dan Smith > Assignee: Dan Smith > > In the case of an HARegion, AbstractRegionMap.initialImagePut deserializes > the value to set the haContainer. Normally, that value is a wrapped by a > VMCachedDeserializable, and deserializing it replaces it in the > VMCachedDeserializable. With -Dgemfire.PREFER_SERIALIZED=true, the value is > wrapped by a PreferBytesCachedDeserializable and deserializing it creates a > copy of the value. It doesn't replace it in the > PreferBytesCachedDeserializable. > So, in this case, the haContainer is being set on a copy of the value, not > the value itself. It has no effect, and the value put into the HARegion has > no haContainer. > This is not really an issue until this member needs to provide an initial > image for another member. > At that time, a NullPointerException like this occurs: > {noformat} > [vm3] Caused by: java.lang.NullPointerException > [vm3] at Remote Member '172.16.115.245(73551)<v3>:32772' in > org.apache.geode.internal.cache.tier.sockets.HAEventWrapper.toData(HAEventWrapper.java:287) > [vm3] at Remote Member '172.16.115.245(73551)<v3>:32772' in > org.apache.geode.internal.InternalDataSerializer.invokeToData(InternalDataSerializer.java:2299) > [vm3] at Remote Member '172.16.115.245(73551)<v3>:32772' in > org.apache.geode.internal.InternalDataSerializer.writeDSFID(InternalDataSerializer.java:1406) > [vm3] at Remote Member '172.16.115.245(73551)<v3>:32772' in > org.apache.geode.internal.InternalDataSerializer.basicWriteObject(InternalDataSerializer.java:2067) > [vm3] at Remote Member '172.16.115.245(73551)<v3>:32772' in > org.apache.geode.DataSerializer.writeObject(DataSerializer.java:2936) > [vm3] at Remote Member '172.16.115.245(73551)<v3>:32772' in > org.apache.geode.internal.util.BlobHelper.serializeToBlob(BlobHelper.java:53) > [vm3] at Remote Member '172.16.115.245(73551)<v3>:32772' in > org.apache.geode.internal.cache.EntryEventImpl.serialize(EntryEventImpl.java:1969) > [vm3] at Remote Member '172.16.115.245(73551)<v3>:32772' in > org.apache.geode.internal.cache.EntryEventImpl.serialize(EntryEventImpl.java:1955) > [vm3] at Remote Member '172.16.115.245(73551)<v3>:32772' in > org.apache.geode.internal.cache.PreferBytesCachedDeserializable.<init>(PreferBytesCachedDeserializable.java:69) > [vm3] at Remote Member '172.16.115.245(73551)<v3>:32772' in > org.apache.geode.internal.cache.CachedDeserializableFactory.create(CachedDeserializableFactory.java:82) > [vm3] at Remote Member '172.16.115.245(73551)<v3>:32772' in > org.apache.geode.internal.cache.AbstractRegionMap.initialImagePut(AbstractRegionMap.java:778) > [vm3] at Remote Member '172.16.115.245(73551)<v3>:32772' in > org.apache.geode.internal.cache.InitialImageOperation.processChunk(InitialImageOperation.java:928) > [vm3] at Remote Member '172.16.115.245(73551)<v3>:32772' in > org.apache.geode.internal.cache.InitialImageOperation$ImageProcessor.process(InitialImageOperation.java:1249) > [vm3] at Remote Member '172.16.115.245(73551)<v3>:32772' in > org.apache.geode.distributed.internal.ReplyMessage.process(ReplyMessage.java:213) > [vm3] at Remote Member '172.16.115.245(73551)<v3>:32772' in > org.apache.geode.internal.cache.InitialImageOperation$ImageReplyMessage.process(InitialImageOperation.java:2725) > [vm3] at Remote Member '172.16.115.245(73551)<v3>:32772' in > org.apache.geode.distributed.internal.ReplyMessage.dmProcess(ReplyMessage.java:193) > [vm3] at Remote Member '172.16.115.245(73551)<v3>:32772' in > org.apache.geode.distributed.internal.ReplyMessage.process(ReplyMessage.java:186) > [vm3] at Remote Member '172.16.115.245(73551)<v3>:32772' in > org.apache.geode.distributed.internal.DistributionMessage.scheduleAction(DistributionMessage.java:374) > [vm3] at Remote Member '172.16.115.245(73551)<v3>:32772' in > org.apache.geode.distributed.internal.DistributionMessage$1.run(DistributionMessage.java:440) > [vm3] at Remote Member '172.16.115.245(73551)<v3>:32772' in > java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) > [vm3] at Remote Member '172.16.115.245(73551)<v3>:32772' in > java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) > [vm3] at Remote Member '172.16.115.245(73551)<v3>:32772' in > org.apache.geode.distributed.internal.DistributionManager.runUntilShutdown(DistributionManager.java:665) > [vm3] at Remote Member '172.16.115.245(73551)<v3>:32772' in > org.apache.geode.distributed.internal.DistributionManager$5$1.run(DistributionManager.java:961) > [vm3] at Remote Member '172.16.115.245(73551)<v3>:32772' in > java.lang.Thread.run(Thread.java:748) > {noformat} -- This message was sent by Atlassian JIRA (v6.4.14#64029)
