NPE in XSiteAdminOperations --------------------------- Key: ISPN-2731 URL: https://issues.jboss.org/browse/ISPN-2731 Project: Infinispan Issue Type: Bug Components: JMX, reporting and management Affects Versions: 5.2.0.CR1 Reporter: Erik Salter Assignee: Erik Salter Fix For: 5.2.0.Final If an XSite JMX operation fails because of a node being down/suspected, a null response is put into the aggregate map. (We've seen a variation of this where the response is dropped by UNICAST2 and the operation times out before JGroups retransmits it) This causes a NPE in XSiteAdminOperations line 241.
