Richard Achmatowicz commented on JBAS-8710:
-------------------------------------------

Two test cases relating to PreferredMasterElectionPolicy have been fixed:

 1. PreferredMasterElectionPolicyTestCase was faling on testUsePreferredMasterViaAddress(). 

This test case tests what happens when we set up a set of cluster nodes {(localhost, 10000), (localhost, 10001), (localhost,10002)} and then try to set the preferred master using in IP address literal. localhost translates to either 127.0.0.1 or ::1 depending on the settings of java.net.preferIPv4Stack and java.net.preferIPv6Addresses. I made things simple and use 127.0.0.1:10002 if java.net.preferIPv4Stack=true and [::1]:10002 otherwise. 

2. HASingletonElectionPolicyTestCase 

This test was failng as the testcase deployment ha-electionpolicy-jboss-beans.xml was not deploying correctly, due to IPv6 addresses for preferredMaster attribute not being enclosed in square brackets. Fixed the XML descriptor by replacing <property name="preferredMaster">${node0.bind.address}:1099</property> with <property name="preferredMaster">${node0.bind.address.url}:1099</property>

> The bean org.jboss.ha.singleton.PreferredMasterElectionPolicy has an attribute preferredMaster which identified a process in a cluster which should be the master node in a clustered partition.
> The preferred master attriubute is specified in the form host:port.
> This format works fine for IPv4 addresses, but breaks down for IPv6 addresses unless the host part is surrounded with square brackets, according to rfc2732.
> There are two places which above class may break:
> (i) in setting the preferred master attribute
> (ii) in comparing ClusterNode instances using PreferredMasterElectionPolicy.find() to check if a given preferred master is in the current cluster.
