Project: WildFly
Issue Type: Bug
Components: Clustering
Affects Versions: 13.0.0.Beta1

We hit NPE when running tests for RFE EAP7-867.
EAP distribution was built from https://github.com/pferraro/wildfly/tree/scattered .
Test description: Positive stress test (no failover), 4-node EAP cluster, clients:
starting with 400 clients in the beginning, raising the number of clients to 6000 in the
end of the test.
During clean server shutdown in the end of the test, server logged NPE and got stuck:
