Remote listener can fail with NPE --------------------------------- Key: ISPN-4945 URL: https://issues.jboss.org/browse/ISPN-4945 Project: Infinispan Issue Type: Bug Components: Server Affects Versions: 7.0.0.Final Reporter: Vojtech Juranek Assignee: Galder Zamarreño Priority: Critical Fix For: 7.0.1.Final When event sender generates the event, it access metadata which can be {{null}} and thus it fails with NPE: {noformat} [0m09:46:22,182 ERROR [org.infinispan.interceptors.InvocationContextInterceptor] (HotRodServerWorker-7-17) ISPN000136: Execution error:
