Re: [infinispan-dev] NPE in MapReduceTask running in cluster

NPE ocures while running CapeDwarf cluster tests, see stack below. Null comes from MapReduceTask.invokeEverywhere 13:36:51,053 INFO [org.jboss.as.clustering.infinispan] (http-/192.168.30.248:8080-1) JBAS010281: Started search_capedwarf-test cache from capedwarf container 13:36:51,058 DEBUG [org.infinispan.distexec.mapreduce.MapReduceTask] (http-/192.168.30.248:8080-1) Invoking MapCombineCommand [keys=[], taskId=14c75f18-3861-4a06-8a4a-b1592d542d14] across entire cluster *13:36:51,065 DEBUG [org.infinispan.distexec.mapreduce.MapReduceTask] (http-/192.168.30.248:8080-1) Invoked MapCombineCommand [keys=[], taskId=14c75f18-3861-4a06-8a4a-b1592d542d14] across entire cluster, results are {node-b/capedwarf=null}* 13:36:51,067 DEBUG [org.infinispan.distexec.mapreduce.MapReduceTask] (http-/192.168.30.248:8080-1) Invoking MapCombineCommand [keys=[], taskId=14c75f18-3861-4a06-8a4a-b1592d542d14] locally 13:36:51,069 DEBUG [org.infinispan.distexec.mapreduce.MapReduceTask] (http-/192.168.30.248:8080-1) Invoked MapCombineCommand [keys=[], taskId=14c75f18-3861-4a06-8a4a-b1592d542d14] locally Any idea ?
