We got java.lang.NullPointerException in Clustering tests where a scattered cache is used;
The client fail rate is very low (0.002%);
This is the server configuration:
embed-server --server-config=standalone-ha.xml /subsystem=modcluster/mod-cluster-config=configuration:write-attribute(name=advertise,value=false) /socket-binding-group=standard-sockets/remote-destination-outbound-socket-binding=mod_cluster:add(host=10.0.144.220,port=7000) /subsystem=modcluster/mod-cluster-config=configuration:write-attribute(name=proxies,value=[mod_cluster]) /subsystem=jgroups/channel=ee:write-attribute(name=stack,value=tcp) /subsystem=infinispan/cache-container=web/scattered-cache=testScattered:add() /subsystem=infinispan/cache-container=web:write-attribute(name=default-cache, value=testScattered)
The error happens on node3 right after the first node in cluster (node1) is failed (see eap-7.x-clustering-http-session-shutdown-scattered#134):

Note the error is present also in stress tests where there is no fail-over: for example in run eap-7.x-clustering-stress-session-scattered#92 we have four nodes (node1, node2, node3, node4) and the error happens on nodes 2,3,4 at the end of the test right when node1 receives the stop command:
