[infinispan-issues] [JBoss JIRA] (ISPN-8719) Error "ISPN006016: Factory 'org.infinispan.server.hotrod.HotRodServer$ToEmptyBytesKeyValueFilterConverter' not found in server" when using remoteCache version 9 against infinispan-server version 8

Error "ISPN006016: Factory 'org.infinispan.server.hotrod.HotRodServer$ToEmptyBytesKeyValueFilterConverter' not found in server" when using remoteCache version 9 against infinispan-server version 8 ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- Key: ISPN-8719 URL: https://issues.jboss.org/browse/ISPN-8719 Project: Infinispan Issue Type: Bug Affects Versions: 9.2.0.CR1 Reporter: Marek Posolda Assignee: William Burns Attachments: InfinispanRemote.java Steps to reproduce: 1) Use infinispan server version 8.2.6 (or JDG server 7.1.0) and start it. {code} cd JDG_HOME/bin ./standalone.sh {code} 2) Create sample java project having dependency on latest dependency 9.2.0.CR1 in pom.xml: {code} <dependencies> <dependency> <groupId>org.infinispan</groupId> <artifactId>infinispan-core</artifactId> <version>9.2.0.CR1</version> </dependency> <dependency> <groupId>org.infinispan</groupId> <artifactId>infinispan-cachestore-remote</artifactId> <version>9.2.0.CR1</version> </dependency> </dependencies> {code} 3) Add one simple java class based on the tutorial: http://infinispan.org/tutorials/simple/remote/ . The only difference is that I use hotRod protocolVersion 2.5 and calling: {code} remoteCache.keySet().iterator().hasNext() {code}. I am attaching the class in attachement. 4) Run the class. Seeing exception in both server log and on client-side. Server exception {code} 10:44:20,365 ERROR [org.infinispan.server.hotrod.CacheDecodeContext] (HotRodServerWorker-6-1) ISPN005003: Exception reported: java.lang.IllegalStateException: ISPN006016: Factory 'org.infinispan.server.hotrod.HotRodServer$ToEmptyBytesKeyValueFilterConverter' not found in server at org.infinispan.server.hotrod.iteration.DefaultIterationManager.getFactory(DefaultIterationManager.java:148) at org.infinispan.server.hotrod.iteration.DefaultIterationManager.start(DefaultIterationManager.java:131) at org.infinispan.server.hotrod.ContextHandler.realRead(ContextHandler.java:175) at org.infinispan.server.hotrod.ContextHandler.lambda$channelRead0$1(ContextHandler.java:57) at org.infinispan.server.hotrod.ContextHandler$$Lambda$86/1492247987.run(Unknown Source) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) at io.netty.util.concurrent.DefaultThreadFactory$DefaultRunnableDecorator.run(DefaultThreadFactory.java:144) at java.lang.Thread.run(Thread.java:745) {code} Client exception: {code} Jan 24, 2018 10:44:20 AM org.infinispan.client.hotrod.impl.protocol.Codec20 checkForErrorsInResponseStatus WARN: ISPN004005: Error received from the server: java.lang.IllegalStateException: ISPN006016: Factory 'org.infinispan.server.hotrod.HotRodServer$ToEmptyBytesKeyValueFilterConverter' not found in server Exception in thread "main" org.infinispan.client.hotrod.exceptions.HotRodClientException:Request for messageId=5 returned server error (status=0x85): java.lang.IllegalStateException: ISPN006016: Factory 'org.infinispan.server.hotrod.HotRodServer$ToEmptyBytesKeyValueFilterConverter' not found in server at org.infinispan.client.hotrod.impl.protocol.Codec20.checkForErrorsInResponseStatus(Codec20.java:408) at org.infinispan.client.hotrod.impl.protocol.Codec20.readPartialHeader(Codec20.java:162) at org.infinispan.client.hotrod.impl.protocol.Codec20.readHeader(Codec20.java:148) at org.infinispan.client.hotrod.impl.operations.HotRodOperation.readHeaderAndValidate(HotRodOperation.java:60) at org.infinispan.client.hotrod.impl.operations.IterationStartOperation.executeOperation(IterationStartOperation.java:72) at org.infinispan.client.hotrod.impl.operations.IterationStartOperation.executeOperation(IterationStartOperation.java:21) at org.infinispan.client.hotrod.impl.operations.RetryOnFailureOperation.execute(RetryOnFailureOperation.java:56) at org.infinispan.client.hotrod.impl.iteration.RemoteCloseableIterator.startInternal(RemoteCloseableIterator.java:127) at org.infinispan.client.hotrod.impl.iteration.RemoteCloseableIterator.start(RemoteCloseableIterator.java:140) at org.infinispan.client.hotrod.impl.RemoteCacheImpl.retrieveEntries(RemoteCacheImpl.java:162) at org.infinispan.client.hotrod.impl.RemoteCacheImpl.retrieveEntries(RemoteCacheImpl.java:168) at org.infinispan.client.hotrod.impl.RemoteCacheImpl.retrieveEntries(RemoteCacheImpl.java:173) at org.infinispan.client.hotrod.impl.RemoteCacheImpl$KeySet.iterator(RemoteCacheImpl.java:553) at org.mposolda.ispn.InfinispanRemote.main(InfinispanRemote.java:34) {code} Indeed, When looking at this line of class RemoteCacheImpl, I see that it references the class, which seem that it was added in HotRodServer version 9. This looks like the cause of the error: https://github.com/infinispan/infinispan/blob/master/client/hotrod-client...
