Use of AUTH does not result in a SecurityException, but instead nodes create separate clusters with the same name ----------------------------------------------------------------------------------------------------------------- Key: JGRP-2227 URL: https://issues.jboss.org/browse/JGRP-2227 Project: JGroups Issue Type: Bug Affects Versions: 4.0.6 Reporter: Robert Cernak Assignee: Bela Ban Fix For: 4.0.12 Attachments: jgroupsDoesNotThrowSecurityExceptionWithJgroups4012.zip, jgroupsLogs.zip, traceLogs.zip I implemented method org.jgroups.auth.AuthToken#authenticate(AuthToken token, Message msg) in my class and its body contained only one line: return false; In this way authentication should be false and I should get SecurityException. When I started joining of nodes together to form a cluster, instead of getting SecurityException, nodes formed 2 different clusters with the same name. I am sure method was evaluated, since I tried to run it also with breakpoint, which was triggered during joining process.
