ClassCastException processing GravitateDataCommand results in LegacyDataGravitatorInterceptor --------------------------------------------------------------------------------------------- Key: JBCACHE-1524 URL: https://jira.jboss.org/jira/browse/JBCACHE-1524 Project: JBoss Cache Issue Type: Bug Security Level: Public (Everyone can see) Components: Buddy Replication Affects Versions: 3.1.0.GA Reporter: Paul Ferraro Assignee: Manik Surtani Priority: Critical While running web session replication soak tests, we ran into the following failure using synchronous buddy replication. The issue, I think, resides in the LegacyDataGravitatorInterceptor.ResponseValidityFilter, the purpose of which is unclear to me. It does not actually filter out invalid responses, since ResponseValidityFilter.isAcceptable(...) always returns true. Consequently, the response processing in LegacyDataGravitatorInterceptor.gravitateData(Fqn) throws an ClassCastException if a response is not a GravitateResult instance, which was the case in the trace below: 17:42:30,454 ERROR [org.apache.catalina.connector.CoyoteAdapter] (ajp-jawa03%2F10.34.32.155-8009-141) An exception or error occurred in the container during the request processing [JBoss]
