ClassNotFoundException while executing Map/Reduce task over JavaScript which is called from Jar (Server Task) ------------------------------------------------------------------------------------------------------------- Key: ISPN-6303 URL: https://issues.jboss.org/browse/ISPN-6303 Project: Infinispan Issue Type: Bug Components: Server, Tasks, Test Suite - Server Affects Versions: 8.1.2.Final Reporter: Anna Manukyan Assignee: Galder Zamarreño Fix For: 9.0.0.Alpha3, 9.0.0.Final When trying to execute Map/Reduce task over JavaScript which is called from the Jar Task deployed on infinispan-server, the following exception is thrown: {code} java.lang.ClassNotFoundException: org.infinispan.scripting.utils.JSArrays from [Module "org.jgroups.extension:main" from local module loader @33e5ccce (finder: local module finder @5a42bbf4 (roots: /home/amanukya/Documents/Red Hat Workspace/infinispan/server/integration/testsuite/target/server/node2/modules,/home/amanukya/Documents/Red Hat Workspace/infinispan/server/integration/testsuite/target/server/node2/modules/system/layers/base))] at org.infinispan.client.hotrod.impl.protocol.Codec20.checkForErrorsInResponseStatus(Codec20.java:343) at org.infinispan.client.hotrod.impl.protocol.Codec20.readPartialHeader(Codec20.java:132) at org.infinispan.client.hotrod.impl.protocol.Codec20.readHeader(Codec20.java:118) at org.infinispan.client.hotrod.impl.operations.HotRodOperation.readHeaderAndValidate(HotRodOperation.java:56) at org.infinispan.client.hotrod.impl.operations.ExecuteOperation.executeOperation(ExecuteOperation.java:49) at org.infinispan.client.hotrod.impl.operations.RetryOnFailureOperation.execute(RetryOnFailureOperation.java:54) at org.infinispan.client.hotrod.impl.RemoteCacheImpl.execute(RemoteCacheImpl.java:703) at org.infinispan.server.test.task.DistributedServerTaskIT.shouldExecuteMapReduceViaJavaScriptInTask(DistributedServerTaskIT.java:182) {code} The thing is that, the org.infinispan.scripting and org.infinispan modules are added as a dependency to the jar in MANIFEST.MF class, but still it looks for that in org.jgroups.extension:main module. If I am adding the infinispan module dependencies in org.jgroups.extension:main:module.xml , then test passes. You can find the test here (remove @Ignore annotation): https://github.com/infinispan/infinispan/blob/master/server/integration/t... UPDATE: The exception is thrown in case of 2 node deployment with clustered caches. For 1 node deployment with local cache, the test passes properly. The same passing test for LOCAL cache usage is: https://github.com/infinispan/infinispan/blob/master/server/integration/t...
