[infinispan-issues] [JBoss JIRA] (ISPN-8568) ClassNotFoundException with Compat mode and custom Pojos

ClassNotFoundException with Compat mode and custom Pojos -------------------------------------------------------- Key: ISPN-8568 URL: https://issues.jboss.org/browse/ISPN-8568 Project: Infinispan Issue Type: Bug Affects Versions: 9.2.0.Alpha1 Reporter: Gustavo Fernandes Assignee: Gustavo Fernandes Fix For: 9.2.0.Beta2 The cache is configured with: {code:xml} <cache-container name="local"> <modules> <module name="deployment.myTask.jar"/> </modules> <local-cache name="compat"> <compatibility enabled="true"/> </local-cache> </cache-container> {code} The {{myTask.jar}} contains Entity.class that is the Pojo to be stored in the cache. When doing a {code:java} remoteCache.put(1, new Entity()); {code} The error is {noformat} 18:13:42,142 ERROR (main) [TestSuiteProgress] Test failed: LocalServerTestCompatModeIT.shouldRunPriceTask org.infinispan.client.hotrod.exceptions.HotRodClientException:Request for messageId=9 returned server error (status=0x85): java.lang.ClassNotFoundException: org.infinispan.server.test.Entity from [Module "org.infinispan.commons:main" from local module loader @4ae82894 (finder: local module finder @543788f3 (roots: /home/gfernandes/github/infinispan/server/integration/testsuite/target/server/node1/modules,/home/gfernandes/github/infinispan/server/integration/testsuite/target/server/node1/modules/system/layers/base))] {noformat} I noticed that in this case, the Marshaller used is {{GenericJBossMarshaller}} who lives in infinispan-commons, and when asked to de-serialize the pojo in byte[] form, the classloader used is ModuleClassLoader for Module "org.infinispan.commons:main" that does not have visibility of the deployed jar's classes.
